Consider the system of ideal pulley spring and block of mass M. Initially both the springs are in their natural lengths. When the system is released from the state of rest, the maximum downward

displacement of the block of mass 'M' before it comes to rest momentarily for the first time, is :

TestHub · Accepted Answer

Block starts and ends at rest, so Δ K E = 0 . By the pulley constraint each spring stretches x when the block falls x . Energy: m gx = 2 1 ​ k x 2 + 2 1 ​ k x 2 = k x 2 x = k m g ​ . Answer: (C)
