The crate of mass m is pushed to the left until the linear elastic spring of constant k has compressed a distance d from its unstretched length . The crate is released from rest, and friction between the crate and the horizontal surface is negligible.Using the work-energy principle, determine the value of k so that the crate is moving at 3 m/s the instant the spring becomes uncompressed. Use m = 20 kg and d = 0.75 m.
