Two blocks of masses m_(1) = 2kg and m_(2) = 4kg are attached to two ends of a light ideal spring of force constantk = 1000 N//m. The system is kept on a smooth inclined plane inclined at 30^(@) with horizontal. The block m_(2) is attached to a light string whose other end is connected to a mass m_(3) = 1 kg. A force F = 15N is applied on m_(1) and the system is released from rest. Assume initially the spring is at relaxed position and the system is released from rest. Find the (a) maximum extension of the spring. (
