A28.0-g object moving to the right at 20.5 cm/s overtakes and collides elastically with a 11.0-g object moving in the same direction at 15.0 cm/s. find the velocity of each object after the collision. (take the positive direction to be to the right. indicate the direction with the sign of your answer.)

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
