Part C An air-track glider of mass m is attached to the end of a horizontal air track by a spring with force constant k as in (Figure 1). The air track is turned off, so there is friction between the glider and the track. Initially the spring is unstretched, but the glider is initially moving to the left at speed v. The glider moves a distance d to the left before coming momentarily to rest. Use the work-energy theorem to find the coefficient of kinetic friction between the glider and the track. Express your answer in terms of the variables m, v, k, 9, and d.
