A sledge loaded with bricks has a total mass of 17.0 kg and is pulled at constant speed by a rope inclined at 19.9° above the horizontal. The sledge moves a distance of 19.9 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.500.
(a) What is the tension in the rope?
N
(b) How much work is done by the rope on the sledge?
kJ
(c) What is the mechanical energy lost due to friction?
