Physics - NLM Question with Solution | TestHub

The mass of the body which is hanging on the rope attached to the movable pulley is four times as much as the mass of the body which is fixed to the ground. At a given instant the heavier body is released. What is the initial acceleration of block m (in $\mathrm{m}/{\mathrm{s}}^2$ )? (The mass of the pulleys and the ropes are negligible.)
