A force of 200.0 N acts on a 7.20-kg bowling ball for 0.350 s.

Question

Calculate its change in velocity: _

Answer 1

This is an impulse question where we use the relationship

Average Force x Time of Interaction = Change of Momentum

Since the bowling ball does not change its mass, the change in momentum is the mass x change in velocity.

We know the force and the time so we can write

(200 N) x (0.35 s) = (7.2 kg) x (Change in Velocity)

Change in Velocity is therefore 9.7 m/s.

We don't know if it is faster or slower since it depends upon the direction of the force
