A 25-kg block and a 15-kg block can move on the horizontal frictionless surface. The blocks are accelerated by a +20-N force that pushes the larger block against the smaller one. 25 kg 20 N F = EF = mä ΣΕ.- ma ΣΕ,- ma, %3! 15 kg %3D !! = Gm.m, W = mg = uF. a) Determine the common acceleration of the two blocks. b) Draw a free body diagram for each block, showing all the forces acting on it. Note: the forces that each block exerts on the other are an action-reaction pair: Determine the magnitude of the force F that the 25-kg block exerts on the 15-kg c) block.
