A sledge loaded with bricks has a total mass of 17.4 kilogram and is pulled at fix speed by a rope inclined at 20.2 degree above the horizontal. The sledge moves a distance of 19.3 meter on a horizontal surface. The coefficient of kinetic friction between the surface and sledge is 0.500.
(a) Calculate what is the tension in the rope?
N
(b) Calculate how much work is done by the rope on the sledge?
kJ
(c) Calculate the mechanical energy lost due to friction?
