Solve the all parts of given problem:

Problem: Indiana Jones is pushing back a 280 kg box of treasure which slides 4.0 m down a 34° incline and kept from accelerating. The effective coefficient of kinetic friction is 0.36.

Part A: Calculate the force exerted by Jones.

Part B: Calculate the work done by Jones on the treasure box.

Part C: Calculate the work done by the friction force.

Part D: What is the work done by the force of gravity?

Part E: What is the net work done on the treasure box?

I need help to determine the work done by Jones on the treasure box.
