Baseball Collision
Baseball Collision
Kiley is throwing a baseball at an aluminum can, as shown in the drawing below.
Multiple Choice Question
Which statement correctly describes the kinetic energy in this system?
A.
The kinetic energy of the can is the same before and after it is hit by the ball because the can started with no kinetic energy and has no way to gain kinetic energy.
B.
The kinetic energy of the ball is the same before and after it hits the can because the can and the ball transfer equal amounts of kinetic energy to each other during the collision.
C.
The kinetic energy of the can is greater before it is hit by the ball because the can transfers energy to the ball during the collision.
D.
The kinetic energy of the ball is greater before it hits the can because the ball transfers energy to the can during the collision.

The correct statement describing the kinetic energy in this system is:
**D. The kinetic energy of the ball is greater before it hits the can because the ball transfers energy to the can during the collision.**
When Kiley throws the baseball, it has kinetic energy due to its motion. When the ball collides with the can, it transfers some of its kinetic energy to the can, causing the can to move. Before the collision, the ball has kinetic energy while the can is stationary and has none. After the collision, the ball's kinetic energy decreases while the can gains kinetic energy as it begins to move. Therefore, the statement about the ball having greater kinetic energy before the collision and the transfer of energy during the collision accurately describes the situation.
