Two objects are connected by a light string passing over a light frictionless pulley. The object of mass 5.00 kilogram is released from rest. Using the principle of conservation of energy.
(a) Compute the speed of the 3.00 kg object just as the 5.00-kg object hits the ground.
(b) Obtain the maximum height to which the 3.00 kilogram object rises.
