Answer:

(a) 14.5 m/s

(b) 9.5 m/s

Explanation:

Let the speed of the boat in the still water (i.e relative to ground) is [tex]v_0[/tex].

Given that the speed of the boat relative to water, [tex]v_r=12.0[/tex] m/s.

Speed of the water current of the river relative to the ground, [tex]u_0=2.50[/tex] m/s towards east.

(a) When the boat is heading toward the east (in the same direction of the current of the river)

The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is

[tex]v_r=v_0-u_0[/tex]

[tex]\Rightarrow 12=v_0-2.5[/tex]

[tex]\Rightarrow v_0=12+2.5=14.5[/tex] m/s

Hence, the boat's speed relative to the ground when it is heading east, with the current, is 14.5 m/s.

(b) When the boat is heading toward the west (in the opposite direction of the current of the river)

The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is

[tex]v_r=v_0-(-u_0)[/tex]

[tex]\Rightarrow 12=v_0+2.5[/tex]

[tex]\Rightarrow v_0=12-2.5=9.5[/tex] m/s

Hence, the boat's speed relative to the ground when it is heading west, against the current, is 9.5 m/s.

Answer:

6.6 s.

Explanation:

From the question given above, the following data were obtained:

Height (h) = 215 m

Time (t) =..?

Thus, we can obtain the time taken for the ball to get to the ground by applying the following formula:

h = ½gt²

Where:

h is the height.

g is the acceleration due to gravity

t is the time to taken.

With the above formula, the time taken for the ball to get to the ground can be obtained as follow:

Height (h) = 215 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =..?

h = ½gt²

215 = ½ × 9.8 × t²

215 = 4.9 × t²

Divide both side by 4.9

215 / 4.9 = t²

Take the square root of both side.

t = √(215 / 4.9)

t = 6.6 s

Therefore, it will take 6.6 s for the ball to get to the ground.

In a distance time graph, when the x and y values are positive (in first quadrant), the runner is moving forward.

While, if the distance value ( in the y axis) is negative, the runner is moving backwards ( towards the start) .

Hope it helps :)

A distance-time graph shows how far an object has travelled in a certain time. This is a simple line graph that plots observations by distance versus time.

 The distance is transferred to the Y axis.

Time is plotted on the X-axis.

The distance-time graph when we study the motion of bodies. If you set the distance and time of the movement of the object and transfer the same data to a rectangular graph, you will get a distance-time graph corresponding to the movement of the object.

Hi! I am confused

Explanation:

If a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s², then he was moving at  31 m / s at the bottom of the course.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

As given in the problem, a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s² .

By using the first equation of the motion,

v = u + at

v = 1 + 3 × 10

v = 31 m / s

Thus, he was moving at  31 m / s at the bottom of the course.

Answer:

[tex]a=-1.388\ m/s^2[/tex]

Explanation:

Initial velocity of car, u = 50 km/h = 13.88 m/s

It stops, v = 0

Time, t = 10 s

We need to find the car's deceleration while slowing down. As the car is slowing down, it will have deceleration. It can be calculated as follows :

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0-13.88 }{10}\\\\a=-1.388\ m/s^2[/tex]

So, the deceleration of the car is [tex]1.388\ m/s^2[/tex].

Answer:

8 m/s².

Explanation:

We'll begin by calculating the force applied to 0.25 Kg hockey puck. This is illustrated below:

Mass (m) = 0.25 Kg

Acceleration (a) = 16 m/s²

Force (F) =.?

Force (F) = mass (m) × acceleration (a)

F = ma

F = 0.25 × 16

F = 4 N

Therefore, a force of4 N was applied to the 0.25 Kg hockey puck.

Finally, we shall determine the acceleration in which the 4 N force will give to the 0.50 Kg baseball. This can be obtained as follow:

Mass (m) = 0.50 Kg

Force (F) = 4 N

Acceleration (a) =?

F = ma

4 = 0.5 × a

Divide both side by 0.5

a = 4 / 0.5

a = 8 m/s²

Therefore, the same force (i.e 4 N) applied to the hockey puck will give the 0.5 kg baseball an acceleration of 8 m/s².

c) more energy is trapped, which leads to an increase in Earth's global temperature

Explanation:

Greenhouse effect is caused by the trapping of the reflected energy from the surface of the earth into the atmosphere by some gases. Thus with time causes more energy to be trapped in the atmosphere, which cause an increase in the average ambient temperature of the earth. Because the energy could not escape out into space beyond the earth's atmosphere. Therefore, an increase in Earth's global temperature.

Answer:

76.53 kg; 9.15 m/s² left.

Explanation:

Given the following data;

Weight of car = 750N

Applied force = 700N

a) To find mass

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, [tex] Weight, W = mg[/tex]

We know acceleration due to gravity is equal to 9.8 m/s²

Substituting into the equation;

[tex] 750 = m*9.8[/tex]

[tex]Mass, m = \frac{750}{9.8}[/tex]

Mass, m = 76.53kg

b) To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

Making acceleration (a) the subject, we have;

[tex]Acceleration (a) = \frac{F}{m}[/tex]

Substituting into the equation;

[tex]Acceleration (a) = \frac{700}{76.53}[/tex]

Acceleration (a) = 9.15 m/s² left.
