2. a)

A 0.20 kg hockey puck on a frictionless surface is hit with a stick. The force of the stick on the puck, during the 0.4 seconds while they are in contact, causes the puck to go from rest to 36 meters per second east. What was the magnitude of the average force of the stick on the puck while they were in contact?

b)

A 3-kg block is placed on a frictionless ramp-incline, where it slides from rest, 18 m down along the ramp- incline in 4 seconds.

What was the angle of the incline, with respect to the horizontal?

Mastering Physics: Hockey Stick and Puck
A hockey stick of mass ms and length L is at rest on the ice (which is assumed to be frictionless). A puck with mass mp hits the stick a distance D from the middle of the stick. Before the collision, the puck was moving with speed v0  in a direction perpendicular to the stick, as indicated in the figure. The collision is completely inelastic, and the puck remains attached to the stick after the collision.Find the speed vf of the center of mass of the...
