Question: A box of mass 52 kg is pushed up an incline that has a total length of 7.0 m and is tilted 21° away from the horizontal. Assume that the coefficient of kinetic friction between the box and the incline is 0.22, the applied force is in the horizontal direction, and the box moves with a constant speed.
Part A: What is the work done by the applied force?
Part B: What is the work done by the kinetic friction?
Part C: What is the work done by the weight on the box?
(a)_____kJ;
(b)____ kJ;
(c)____ kJ.
I want help to find the work done by the weight on the box.
