consider the collision of two billiard balls: A stationary 8-ball is hit by a cue ball moving with uniform motion. the 8-ball quickly accelerates to some velocity. by newton 2, we can explain that the cue ball exerted an unbalanced external force on the 8-ball and the 8-ball accelerated in accordance with the relation F=ma. we might then part ourselves on the back for phyzjob well done and call it quits for the rest of the day. but wait. what happened to the cue ball? Did the cue ball maintain uniform motion?

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
