Two smooth blocks of mases m_(1) and m_(2) attached with an ideal spring of stiffness k and kept on hrozontal surface. If m_(1) is projected with a horizontal velocity v_(0) . Find the maximum compression of the spring.

Two smooth blocks of mases m_(1) and m_(2) attached with an ideal spring of stiffness k and kept on hrozontal surface. If m_(1) is projected with a horizontal velocity v_(0) . Find the maximum compression of the spring.

The figure shows two blocks of mass m each, connected by an ideal unstretched spring and then placed on a frictionless floor. If the blocks are given velocities v_(0) and 2v_(0) as shown, then the maximum extension in the spring is
