Momentum Collisions and Impulse

Steven rolls a 5.2 kg bowling ball down the lane and hits a 1.2 kg pin at rest. The ball had an initial velocity of 10 m/s before the collision. The pin goes flying off at 8.3 m/s. What is the final velocity of the ball?

Giselle and Brock were hanging out one afternoon. Giselle rolled a 5 kg bowling ball down the sidewalk to the east at 7 m/s. At the same time, Brock threw a piece of 3.8 kg clay to the west and the two objects collide. If both objects come to rest immediately after the collision, what was the speed of the clay before hitting the bowling ball?

How does applying a larger force over a shorter time period affect the impulse delivered to an object?

• It decreases the impulse.

• It increases the impulse.

• It has no effect on the impulse.

• It changes the direction of the impulse.
