If a ball is dropped from a height of 10 m, hits the ground and bounces back up to a maximum height of 7.5 m, describe how the Energy Pie Chart would look. (Use fractions and the storage mode)

In the same situation as above, how would the pie chart look at a height of 5 m (after the bounce but before the max height of 7.5)? (Use fractions and the storage mode)



A cart is speeding on a flat surface towards a spring mounted on a wall. As the cart moves, it slows. When the slowing cart hits the spring, it compresses it fully and the cart comes to rest. If the system consists of the cart, spring, and Earth's field, describe the transfer of energy at the initial and final points.
