A golf ball is hit by a club. The graph shows the variation with time of the force exerted on the bal
by the club.
Which quantity, for the time of contact, cannot be found from the graph?
A the average force on the ball
B the change in momentum of the ball
C the contact time between the ball and the club
D the maximum acceleration of the ball

You can't find the acceleration of the ball. The graph tells the force, but you'd also need to know the mass of the ball.

Answer:

D the maximum acceleration of the ball

Explanation:

A the average force on the ball

Total change in momentum of the ball is area under the graph between force and time

So here average force is the ratio of area under the force time graph and total time of the graph

B the change in momentum of the ball

Total change in momentum of the ball is area under the graph between force and time

C the contact time between the ball and the club

Here total time of contact is the total time for which force is acting on the ball due to wall

D the maximum acceleration of the ball

Here since we do not know about the mass of ball we can not find the acceleration.

So here we have correct answer as

D the maximum acceleration of the ball
