An object of unknown mass is initially at rest and dropped from a height h. it reaches the ground with a velocity v sin θ / g 1. the same object is then raised again to the same height h but this time is thrown downward with velocity υ1 it now reaches the ground with a new velocity υ2. how is v2 related to v1?

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
