Two blocks of mass 4 kg and 3 kg are each initially 7 m above the ground and they are connected with each other by massless cord that passes over massless and frictionless pulley. The pulley is 20 m above the ground. 3.0 s after system is released, a naughty boy cuts the cord. What maximum height does the lighter object reach after the system is released?
