A block of stone, with a mass m = 4000 kg, is being carried on a trolley. It is to be held at rest by a mass m supported on a tray. The tray is attached to the trolley by a rope supported over a pulley. The ramp makes an angle = 35 with the horizontal, and the rope is parallel to the ramp and has the same tension throughout its entire length. Assume that the mass of the trolley and the mass of the tray are negligible compared to me and m2. m 0 m
