k= 35 N/m 50 cmThe spring provided in the image has an unstretched length of 60 cm. If it is confined by a small plate and awall, so that the length of confinement is 50 cm, determine the initial speed of the 2 kg block in A. Assume that the spring is farther compressed 5 cm when the block momentarily stops. The stiffness constant of the spring is 35 N/m.
