mass-spring system is initially compressed towards a wall and hold in equilibrium withthe help of a force F. At time t=0sec, 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
A mass-spring system is initially compressed towards a wall and hold in equilibrium withthe help of a force F. At time t=0sec, 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 Δt. Express your answerin terms of k,m,Δt and F.
