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.

A,B,C, and D are four trees, located at the vertices of a square (Fig. 5.117). Wind blows from A to B with uniform speed. The ratio of times of flight of a bird from A to B and from B to A is n. At what angle should the bird fly from the direction of wind flow, in order that it starts from A and (a) reaches C, (b) reaches D ?
