A 4.4-kg block begins at rest and accelerates to a velocity of 0.25m/s in 0.50s. Determine the acceleration and net force acting on the block ?

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

Amira pulls a 3 pound wagon 4 feet. how much work has she done?

It is really hard for me right know
