Answer:
V = 5.96 m/s
Explanation:
First we find the force required to move the car up the inclined plane. This force shall be equal to the component of the weight of the car that is parallel to the inclined plane. Hence,
F = W Sin θ
F = mg Sin θ
where,
F = Force = ?
m = mass of car = 1600 kg
g = 9.8 m/s²
θ = Inclination Angle = 20°
Therefore,
F = (1600 kg)(9.8 m/s²) Sin 20°
F = 5362.87 N
Now, we use power formula:
P = FV
V = P/F
where,
P = Engine Power = 32000 W
V = Maximum Velocity of Car = ?
Therefore,
V = 32000 W/5362.87 N
<u>V = 5.96 m/s</u>
Newton's third law says that for every action, there is an equal and opposite reaction. So if your friend's bumper car, both of you will go flying back at the same force in opposite directions.
Hope this helps.
