The masses of blocks A and B in figure-2...

The masses of blocks A and B in figure-2.24 are 20 kg and 10 kg, respectively. The blocks are initially at rest on the floor and are connected by a massless string passing over a massless and frictionless pulley. An upward force F is applied to the pulley. Find the acceleration `a_(1)` and `a_(2)` of the two blocks A and B when F is (a) 124 N (b) 294 N (c ) 424 N.

`[(a)0,0(b)0,4.7m//s^(2), (c ) 0.6m//s^(2),11.2 m//s^(2)]`
