Two pucks, each of mass m, are connected by a massless string of length 2l as illustrated below. the pucks lie on a horizontal, frictionless sheet of ice. the string is initially straight (i. e., θ = 90o ). a constant, horizontal force f is applied to the middle of the string in a direction perpendicular to the line joining the pucks. when the pucks collide, they stick together. how much mechanical energy is lost in the collision?
