A sledge loaded with bricks has a total mass of 17.1 kg and is pulled at constant speed by a rope inclined at 19.9° above the horizontal. The sledge moves a distance of 19.6 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.5

find the tension of the rope?

how much work is the roping doing on the sledge.

what is the mechanical energy lost due to friction.
