Compute all parts of following problem:

Problem: A sledge loaded with bricks has a total mass of 17.7 kg and is pulled at constant speed by a rope inclined at 20.9° above the horizontal. The sledge moves a distance of 19.5 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.500.

Part A: What is the tension in the rope?

Part B: How much work is done by the rope on the sledge?

Part C: What is the mechanical energy lost due to friction?

I want help to find the mechanical energy lost due to friction.
