A sledge loaded with bricks has a total mass of 18.5 kilogram and is pulled at constant speed by a rope inclined at 20.0Â degree above the horizontal. The sledge moves a distance of 20.3 meter on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.500.
(a) Evaluate what is the tension in the rope?
N
(b) Determine how much work is done by the rope on the sledge?
kJ
(c) Find what is the mechanical energy lost due to friction?
