A sledge loaded with bricks has a total mass of 18.1 kg and is puled at a constant speed by a rope inclined at 19.0^above The horizontal. The sledge moves a distance of 20.7 m on a horizontal surface. The coefficient of kinetic friction between the slegde 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?
