A 0. 058–kg golf ball that is sitting still is struck by a club that produces a force of 172 N. The club gives the ball a momentum of 12 kg m/s.



For how long was the club in contact with the ball?

Answer :

The club was in contact with the ball for 0.013 seconds.

To solve this, we can use the following equation:

F * t = ∆p

Where:

- F is the force

- t is the time

- ∆p is the change in momentumWe know that F = 172 N, ∆p = 12 kg m/s, and we want to find t.

Solving for t, we get:

t = ∆p / F

t = 12 kg m/s / 172 N

t = 0.013 s
