Which expression has the same dimensions as an expression yielding a value for acceleration (m/s2)? (delta v has units of m/s.) Group of answer choices delta v/(delta t)^2 (delta v)^2/delta y (delta v)^2/delta t delta v/(delta y)^2

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
