Homework Help: Physics

Posted by Anonymous on Friday, October 22, 2010 at 12:30pm.

Three blocks on a frictionless horizontal surface are in contact with each other, as shown below. A force F is applied to block A (mass mA).
(a) Draw a free-body diagram for each block. Determine (b) the acceleration of the system (in terms of mA, mB, mC), (c) the net force on each block, and (d) the force of contact that each block exerts on its neighbor. (e) If mA = mB = mC =12.0kg and F=96.0N, give numerical answers to (b),(c), and(d). Do your answers make sense intuitively?
