Asmall object is placed at the top of an incline that is essentially frictionless. the object slides down the incline onto a rough horizontal surface, where it stops in 5.0 s after traveling 60 m. a) what is the speed of the object at the bottom of the incline and its acceleration along the horizontal surface? b) what is the height of the incline?

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
