A 250-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
