a golf club exerts and average force of 1000N on a 0.045-kg golf ball which is initially at rest. the club is in contact with the ball for 1.8ms. what is the speed of the golfbal ass it leaves the tee?

a batter applies an average force if 8000N to a baseball for 1.10ms. what is the magnitude of the impulse delivered to the baseball ?

1. Impulse = (force)(time) = change of momentum = m(change of velocity)

Solve that for the final velocity

2. Use the same equation, but in this case you just want the impulse: force x time
