A rubber ball is dropped onto a table and bounces back up. The table exerts a force F on the ball. Which graph best shows the variation with time t of the force F for the short time that the ball is in contact with the table?

1. AGraph A: F increases linearly from zero
2. BGraph B: F starts high, decreases to a minimum, then increases
3. CGraph C: F starts at zero, rises to a maximum, then falls back to zero
4. DGraph D: F starts high and decreases linearly to zero
