<span>So we want to know why is a car racetrack built with a steep inward slope. When a car is moving on a circular path, it experiences a centrifugal force. This force is bigger as the car speed rises. So to counteract that force the steep inward slope is creating a force component towards the center of the circle that comes from the car's own weight so the car doesn't slide off the road. </span>
Answer:
projectile
Explanation:
when an object is released from certain height to ground due to gravity is called projectile
Answer: Potential energy
Explanation: Elastic potential energy; potential energy; P.E.
Answer:29.41 m/s
Explanation:
Given
Height of cliff 22.8 m
Height of river bank=2.4 m
width of river=60.0 m
Car can considered as projectile
Time travel to cover vertical distance=22.8-2.4=20.4 m
t=2.04 s
Range=60 m
Let u be the speed of car
ut=60
