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.
N
Part B: Calculate the work done by Jones on the treasure box.
J
Part C: Calculate the work done by the friction force.
J
Part D: What is the work done by the force of gravity?
J
Part E: What is the net work done on the treasure box?
J
I need help to determine the work done by Jones on the treasure box.
