A mass-spring system is initially compressed towards a wall and hold in equilibrium with the help of a force F . At time t=0 sec, the force F is suddenly released. The mass- spring system then reaches a velocity v while sliding on the frictionless surface. (a) What is the work done by the wall on the mass-spring system as the force F is released? (b) Is the energy of the mass-spring system conserved? Why? (c) Calculate the v in terms of k,m and F. (d) Is the linear momentum conserved? (e) Calculate the average force exerted by the wall on the mass-spring system after the force F is released, assuming that the spring remains in contact with the wall for a short time At . Express your answer in terms of k,m,At and F. be fore af ter t = o t-o wwf WWH m
