A sledge loaded with bricks has a total mass of 18.1 kg and is pulled at constant speed by a rope. Therope is inclined at 20.9° above thehorizontal, and the sledge moves a distance of 21.0 m on a horizontal surface. The coefficient ofkinetic friction between the sledge and surface is 0.500.

a) What is the tension of the rope?

b) How much work is done on the sledge by the rope.

c) what is the energy lost due to friction?
