Three sleds are being pulled horizontally on frictionless horizontal ice using horizontal ropes. The pull is of magnitude 125 N. Find the acceleration of the system.

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

If steel is more dense that lake water, why can a boat float

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
