a disc of mass 50 g slides with zero initial velocity down an inclined plane set at an angle 30 degrees to the horizontal. Having traversed a distance of 50 cm along the horizontal plane , the disc stops . Find the work done by the friction forces over the whole distance , assuming friction coefficient 0.15 for both horizontal and inlined planes . take g = 10 m/s^2
