The example of kinetic energy transfer in the given options is Xavier pushing Brad down the snowy hill on a sled.
To determine which of the given options is an example of kinetic energy transfer, we need to understand what kinetic energy is. Kinetic energy is the energy possessed by an object due to its motion. An object in motion has kinetic energy, while an object at rest does not.
Let's analyze each option:
1. A large snowball sitting at the top of a hill: This option does not involve any motion, as the snowball is simply sitting at the top of the hill. Therefore, it does not demonstrate kinetic energy transfer.
2. Xavier pushing Brad down the snowy hill on a sled: This option involves Xavier exerting force on Brad, causing the sled to move down the snowy hill. The sled's motion accounts for kinetic energy, and the energy is transferred from Xavier to the sled and Brad. Hence, this option exemplifies kinetic energy transfer.
3. A car parked on a steep hill: In this option, the car is parked, which means it is not in motion. Therefore, there is no kinetic energy transfer involved here.
4. Jules sitting in a chair: This option does not demonstrate any motion or kinetic energy transfer, as Jules is sitting and not moving.
Based on the explanations above, the correct option for an example of kinetic energy transfer is the second option: Xavier pushing Brad down the snowy hill on a sled.
