Two hockey pucks, labeled a and b, are initially at rest on a smooth ice surface and are separated by a distance of 18.0 m . simultaneously, each puck is given a quick push, and they begin to slide directly toward each other. puck a moves with a speed of 3.10 m/s , and puck b moves with a speed of 3.50 m/s . what is the distance covered by puck a by the time the two pucks collide?

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
