Answer:

280

Explanation:

I used the equation for momentum, p=mv

70 x 4 = 280

Answer:

13.3 m/s

Explanation:

KE = 1/2 m • v^2

KE = 1/2 • 1140 kg • (13.6m/s )^2

KE = 105427.2 J

KE after brakes are slammed = 105427.2 J - 5000 J

KE after brakes are slammed = 100427.2 J

100427.2 J = 1/2 • 1140 • v^2

v = (100427.2 J • 2 / 1140 kg)^1/2

v = 13.3 m/s after adjusting for significant figs

Answer: If the cue ball strikes a stationary billiard ball straight on, then the cue ball will stop moving after the collision. It will have transferred all of its kinetic energy to the other ball, which will move forward with the same velocity that the cue ball had before the collision.

Explanation:

Answer:

I would assume that the box slows down due to the frictional force between the floor and the box. In addition, the frictional force points opposite of the boxes motion. As we know, the box was given an initial speed, therefore, having an applied force. Hence, we can conclude that  the frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.

Hope that helps!

Answer:

15 cups of flour to make 60 cookies

Explanation:

first, do 60 divided by 25.

then we MULTIPLY the recipe by 2.5

24x2.5=60 amount of cookies

4x2.5=10 cups of sugar

6x2.5=15 cups of flour

15 cups of flour to make 60 cookies

:DDD

Answer:

15 cups of flour

Explanation: 60 times 6 = 360

24x=360

360 divided by 24 is 15.

Answer:

When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

The velocity of the car is equal to 20 m/s.

Given the following data:

Scientific data:

To determine the velocity of the car:

First of all, we would calculate the mass of the car by using this formula:

[tex]Weight = mg\\\\40000=m \times 10\\\\m=\frac{40000}{10}[/tex]

Mass, m = 4,000 kg.

For the velocity:

Mathematically, momentum is giving by this formula;

[tex]Momentum = mass \times velocity[/tex]

Making velocity the subject of formula, we have:

[tex]Velocity = \frac{Momentum}{Mass}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Velocity = \frac{80000}{4000}[/tex]

Velocity = 20 m/s.

Answer:

13.8 billion years ago

Explanation:

The normal force of the passenger cars is 11,760 N.

The normal force of the trucks is 352,800 N.

The normal force of an object is the upward force of the object due to its weight acting downwards.

The normal force of the passenger cars is calculated as follows

Fₙ = mg

Fₙ = 1200 x 9.8

Fₙ = 11,760 N

The normal force of the trucks is calculated as follows;

Fₙ = mg

Fₙ = 36,000 x 9.8

Fₙ = 352,800 N

Answer:

Three lunar eclipses every year.

Explanation:

A lunar eclipse only occurs during a full Moon, when the Sun, Earth and Moon are all aligned. But despite the Moon only taking 29.5 days to orbit Earth and complete a cycle from full Moon to full Moon, there are only on average about three lunar eclipses every year.

When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

Answer:

If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards

Answer: Gases

Explanation: Gases don't have a certain direction, so they go in all directions.

Answer: Voltage = (current) x (resistance)

Voltage = (1.5 A) x (2 ohms)

In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE 3 volts from the battery.
