A2kg block and an 8kg block are connected by a relaxed horizontal spring with spring-constant 300n/m. you pull the 8kg block with some constant horizontal force. there is a coefficient of kinetic friction between the blocks and the floor of μk = 0.3. after a time, the spring is stretched a certain constant amount, and the system moves with constant velocity. (a) draw free-body diagrams for both blocks. (b) what pulling force did you apply? (c) how much is the spring stretched?

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
