Problem
Block A of mass 2.0kg is in contact with block B of mass 3.0kg on a horizontal surface that is essentially frictionless. A constant horizontal force of magnitude 25N is applied to block A, pushing both blocks to the right.
(a) Calculate the magnitude of the acceleration of the two-block system.
(b) Determine the magnitude of the contact force exerted by block A on block B while the blocks accelerate.
(c) Indicate the direction of the force calculated in part (b) on each block, and explain how your directions are consistent with Newton’s third law.
