Three blocks A, B,and C of masses m 1 ,m 2 , and m 3 ,respectively, are resting one on top of the other as shown in Fig.6.24. A horizontal force F is applied on block B. Assuming all the surfaces are frictionless, calculate (1) acceleration of block A, block B, and block C; (2) normal reactions between A and B, B and C, and between C and ground.
