A mass is sliding on a frictionless surface with a speed v. It runs into a linear spring with a spring constant of k, which compresses from position xi to position xf. a)Write a general expression for the force that the spring exerts on the mass, in term of k and x. Choose the initial position of the front of the spring to be xi=0. b)Solve for the numerical value of the work done in Joules given that xi = 0, xf = 62 cm, and k = 110 N/m
