Answer:

So sorry I found the answer a while ago but forgot!

Explanation:

Answer:

m g sin theta = force of object along incline due to gravity

N μ = frictional of incline on object where N is the normal force

N = m g cos theta     force perpendicular to incline

m g sin theta = N μ = μ m g cos theta

μ  = tan theta = tan 38 = .78

Answer:

I'm not to sure but I think the answer is 1.5m/s^2

Explanation:

Acceleration = Change in Velocity over Time.

So we get 15 - 0.0 divided by 10.0 which = 1.5m/s^2

a) The expression to determine the velocity of cart A is [tex]v_{A} = 2\cdot \sqrt{g\cdot H}[/tex].

b) The expression to determine the velocity of cart B is

[tex]v_{B} =\sqrt{2\cdot g\cdot H }[/tex].

c) The final velocity of the carts after the collision is [tex]v = \left(\frac{1-\sqrt{2}}{3} \right)\cdot \sqrt{g\cdot H}[/tex].

d) The collision is inelastic since a part of the energy of the entire system is lost when they stick together.

In this question we shall apply principle of energy conservation and principle of linear momentum conservation to model an inelastic collision between two carts.

a) The combination of cart and ramp can be considered a conservative system as there are no non-conservative forces (i.e. friction), the final velocity of cart A ([tex]v_{A}[/tex]) is related to the change in gravitational potential energy:

[tex]\frac{1}{2}\cdot M\cdot v_{A}^{2} = M\cdot g \cdot 2\cdot H[/tex] (1)

Now we clear [tex]v_{A}[/tex] and simplify the resulting expression:

[tex]v_{A} = 2\cdot \sqrt{g\cdot H}[/tex]

The expression to determine the velocity of cart A is [tex]v_{A} = 2\cdot \sqrt{g\cdot H}[/tex]. [tex]\blacksquare[/tex]

b) We apply the same approach used in part b) to find the final velocity:

[tex]\frac{1}{2}\cdot (2\cdot M) \cdot v_{B}^{2} = (2\cdot M)\cdot g \cdot H[/tex] (2)

Now we clear [tex]v_{B}[/tex] and simplify the resulting expression:

[tex]v_{B} =\sqrt{2\cdot g\cdot H }[/tex]

The expression to determine the velocity of cart B is

[tex]v_{B} =\sqrt{2\cdot g\cdot H }[/tex]. [tex]\blacksquare[/tex]

c) The final velocity ([tex]v[/tex]system is determined by principle of linear momentum conservation:

[tex]3\cdot M\cdot v = M\cdot 2\cdot \sqrt{g\cdot H}-2\cdot M\cdot \sqrt{2\cdot g\cdot H}[/tex]

[tex]3\cdot v = 2\cdot (1-\sqrt{2})\cdot \sqrt{g\cdot H}[/tex]

[tex]v = \left(\frac{1-\sqrt{2}}{3} \right)\cdot \sqrt{g\cdot H}[/tex]

The final velocity of the carts after the collision is [tex]v = \left(\frac{1-\sqrt{2}}{3} \right)\cdot \sqrt{g\cdot H}[/tex]. [tex]\blacksquare[/tex]

d) The collision is inelastic since a part of the energy of the entire system is lost when they stick together. [tex]\blacksquare[/tex]

Answer:

In Newton’s first law, an object at rest remains at rest until an external force isapplied. When I play soccer, the soccer ball will be at rest on the field (the initial condition) andremain in that spot on the field until I kick it (my muscles applying an external force to the ball).According to Newton’s second law, force = mass x acceleration (F=ma). When I kick the resting soccer ball, which has a given mass, it will accelerate in the direction that I kick it. From the equation, acceleration = force divided by mass. Therefore, since the mass of the soccer ball is fixed, the stronger my leg is and the more force I can apply to the ball, the faster it willaccelerate.According to Newton’s first law, an object in motion remains in motion until an external force isapplied. After I kick the soccer ball, it will continue in motion in the direction that I kicked it,but its acceleration will gradually slow down due to the external forces of friction from the airand the surface of the field. According to Newton’s third law, for every action there is an equal and opposite reaction.When I kick the soccer ball forward, if I also kick it in an upward direction, such as a thirty-degree angle from the field, it will come down at an angle when it strikes the field. When theball lands and strikes the field, there will be an equal and opposite reaction whereby instead oftraveling downward it will bounce of the surface of the field and will then be travelling upward.

Answer:

-5.3 m

Explanation:

Consider north to be the positive direction, and south to be the negative direction. Adding up the displacements gives

(+2.1m) + (-7.4m) = 2.1 - 7.4m = -5.3m (southward direction)

This makes sense because if he travels 2.1 m north, then 7.4 south, he would end up south of where he started because he passed 2.1 m and went further

Regardless of where the cars are in the loop, centripetal force is always directed toward the center of rotation. So even if a car you're riding in is at the top of a loop, upside-down, you will feel pressed into your seat.

S = Distance/ Time

= m/s

Same for velocity but instead of distance displacement takes place

S = Displacement/ Time

= m/s

Since the focal length of the lens is 35 cm, at a distance of 35 cm from the lens, no image is formed.

Lenses are portions of a transparent medium bounded by two curved surfaces or one curved surface and one plane surface.

Lenses are used to produce images of an object on. screen.

The images produced may be real or virtual.

For diverging lenses, images produced are always virtual.

For a converging lens, images produced may be virtual or real.

However, when an object is placed exactly at the focal length of a lens, no image is produced.

Therefore, the distance X when no image will be produced in the lens is the focal length of the lens, 35 cm.

A convex mirror is a hollow spherical is divided into pieces the exterior surface of each cut portion is painted. The image of the plant has real, inverted, and smaller image characteristics.

When a hollow spherical is divided into pieces and the exterior surface of each cut portion is painted, it forms a mirror, with the inner surface reflecting the light.

A concave mirror is a name for this sort of mirror. An enlarged and fake image is caused when the concave mirror is positioned too near to the object.

When the distance between the item and the mirror is increased, however, the size of the image decreases, and a true picture is generated. The picture created by the concave mirror may be manipulated.

The magnifying glass represents one of the simplest, most direct applications of a converging lens. As light enters the lens, it becomes focused to a specific focal point in front of the center of the lens. Once you bring the magnifying glass to the optimal distance, so the focal point reaches the object, the object will appear at maximum magnification. Move the glass farther from the object and it will become distorted; move the glass closer to the object and it will decrease in magnification.

Divergent lenses are used on flashlights to magnify the light produced by the bulb. The light falls on the concave side of the lens, and the rays diverge on the other side, thereby increasing the apparent radius of the light source and providing a wider beam.

Answer: The motion of the earth around the sun in its orbit is known as revolution. The earth takes 365.26 days to complete one revolution. The different seasons we experience in a year are a result of this revolution. At the same time, the earth's motion about its own axis has termed the rotation of the earth.

Explanation:

Based on the data provided;

Elastic collisions are collisions in which both energy and momentum is conserved.

Inelastic collisions are collisions in which only momentum is conserved but a decrease in the energy ofthe system occurs.

Applying the law of conservation of energy and the principle of conservation of momentum;

a. the kinetic energy, hence, the final velocity, v, of cart A is related to the change in gravitational potential energy

1/2mv^2 = mgh

v = 2√gh

b. the kinetic energy, hence, the final velocity, v, of cart B is related to the change in gravitational potential energy

1/2mv^2 = mgh

v = 2√gh

c. From the principle of conservation of linear momentum, momentum before and after collision is conserved.

Let the final velocity be v

3M × v = M × 2√gh - 2M × 2√gh

3v = 2(1 - √2) ×√gh

v = {(1 - √2/)3} ×√gh

d. Since the two cars stick together after collision, the collision is inelastic collision.
