The block of mass m1 = m0 is attached to a spring of elastic constant k = (m0g)/H and natural length negligible. In addition, it is connected by an ideal string to another mass m2 = 2m0. The friction in the system is negligible. If the system is released from rest when x = 0. Determine: a) The speed of the blocks when x = H . b) The maximum displacement reaches by block m1.
