The driver of a car traveling at a speed of 25.5 m/s slams on the brakes and comes to a stop in 3.4 s. if we assume that the car's speed changed at a constant rate (constant net force), find the following. what was the car's average speed during this 3.4 s interval? m/s
how far did the car go in this 3.4 s interval? m

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
