Question

A Ping-Pong ball moving East at a speed of 4 m/s collides with a stationary bowling ball. The Ping-Pong ball bounces back to the West, and the bowling ball moves very slowly to the East. Which object experiences the greater magnitude impulse during the collision?

A car hits another and the two bumpers lock together during the collision. Is this an elastic or inelastic collision?

In a game of pool, the white cue ball hits the #5 ball and stops, while the #5 ball moves away with the same velocity as the cue ball had originally. The type of collision is...

In an inelastic collision, the final total momentum is...

When a cannon fires a cannonball, the cannon will recoil backward because the.....

Answer 1

Number 1)

They both experience the same impulse. This is from the Impulse - Momentum Thearen and Newton's Third Law

Number 2)

This is inelastic, they stick together (Elastic means they would bounce)

Number 3)

Perfectly Elastic

Number 4)

Equal to the initial momentum total. (Momentum is conservted)

Number 5)

The cannon ball moves forward and total momentum must be conserved. It was zero at the start, so if the cannon ball moves forward, the cannon must move backward to cancel it out so the net momentum after is also zero.
