Question
A light inextensible string that goes over a smooth fixed pulley as shown in the figure connects two blocks of masses 0.36 kg and 0.72 kg . Taking $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$, find the work done (in joules) by the string on the block of mass 0.36 kg during the first second after the system is released from rest.
