# Force vs. Time Graph: Tennis Ball Hits a Racquet

APPH12-H2MLRJ

A $0.058\ \text{kg}$ tennis ball is traveling to the right at $5.0\ \text{m/s}$ and strikes a $0.30\ \text{kg}$ tennis racquet being held by a child. The force on the racquet as a function of time is shown in the graph below (to the right is defined as the positive direction).

What is the change in kinetic energy of the tennis ball as a result of its collision with the tennis racquet?

A

$-0.85\ \text{J}$

B

$0.090\ \text{J}$

C

$4.5\ \text{J}$

D

$5.1\ \text{J}$
