Describe the transformations between potential and kinetic energy thatoccur when the car rolls to the bottom of the hill and continues rolling.Q8. How is the previous problem different from ones where the object comes to a stop at the end of moving/falling? Discuss what happens tothe energy in each case and how they are different.09. Describe the transformations between potential and kinetic energy that occur when a 1000 kg rock falls from the top of a 18 meter cliff.Q10. How much kinetic energy does a 2000 gram ball have the instant before it hits the ground after falling from a height of 6 meters?Q11. Assume the collision in problem 10 is perfectly elastic (no energy is lost) and there is no air friction. How high should the ball bounce?Describe the transformations between potential and kinetic energy that will occur from when the ball is dropped till it reaches the top of it'sfirst bounce.
