problems connected with pulleys can be solved in two ways:

1] constant string or thread or rope length method

2] instantaneous centre method.

Of these, [1] is easier, calculate total length and equate to contant, then differentiate to get velocity and another differentiation will give u acceleration relations.

Once u know accln relation, draw FBD of each part to find the unknown term/s.

Hope this is helpful to u.

thanks

in ths problm there z constraint of constant string length.........

as there is constant string lenght so thr z constant velocity ant constant acceleration of both the blocks.........

horizontal vel and acceleration of one is equal to the vertical vel of other...........
