Solve the given question:
Question: A box the mass 52kg is pushed up an incline that has a total length of 7.0m and is tilted 21 degrees away from the horizontal. Assume that the coefficient of the 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 weight on the box?
Please show all work to calculate the work done by the weight on the box.
