Indiana Jones is pushing back a 290 kg box of treasure which slides 4.6 m down a 27° incline and kept from accelerating. The effective coefficient of kinetic friction is 0.34
(a) Calculate the force (newtons) exerted by Jones.
(b) Calculate the work (joules) done by Jones on the treasure box.
(c) Calculate the work (joules) done by the friction force.
(d) What is the work (joules) done by the force of gravity?
(e) What is the net work (joules) done on the treasure box?
