A 0.750 kg billiard ball, is thrown at a 0.050 kg golf ball. The Billiard
ball is moving at 22 m/s to the right. After the billiard ball hits the golf
ball, the golf ball moves moves at 54.38 m/s to the right.
a)With what velocity was the golf ball initially moving?
b)With what velocity was the billiard ball moving after the collision?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
