A 290kg metal box is on an incline of 29 degrees and slides down4.3 m. It is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coeff of kinetic friction is 0.40.
1) Net work on the metal box (J)
2) Work done by friction force (J)
3) Compute the force exerted by the man (in N)
4) What is the work done by the force of gravity? (J)
5) Work done with the man on the metal box (in J)
