A tractor is pulling a sled with a load on it a distance of 250m. The tractor exerts a constant pulling force 50KN at angle Ø =30" degree above the horizontal. A 2.5kJ work due to the friction force opposes the sled's motion (friction force is 0.15 of the value of the normal force). What is the total weight of the sled and the load on it if you know that the total work equals to 25KJ?

A tractor is pulling a sled with a load on it a distance of 250m. The tractor exerts a constant pulling force 50KN at angle Ø =30° degree above the horizontal. A 2.5kJ work due to the friction force opposes the sled's motion (friction force is 0.15 of the value of the normal force). What is the total weight of the sled and the load on it if you know that the total work equals to 25kJ?
