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 g = 10 m/s2, 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.



Correct answer is '8 Joules'. Can you explain this answer?

2mg − T = (2m)a
T − mg = ma
⇒ a = g/3
T = 4mg/3    
w = T × s
= T × 1/2at2
= 4/3mg * 1/2 * g/3 * 12
= 200/9 * 0.36
= 8 Joules
