Two blocks are connected by a light string that passes over a frictionless pulley as shown in the figure. The block of mass, m1 = 6 kg, lies on a horizontal surface and is connected to a spring constant of force 30 N/m. The system is released from rest when the spring is at equilibrium (unstretched). If the hanging block of mass, m2 = 10 kg, falls a distance of h = 6 meters before coming to rest, calculate A) the kinetic friction between the block (m1 = 6 kg) and the surface. B) the work done by the light string on m2 C) the total work done on m1
