A box of 70 kg is pulled up an incline measured 40 degrees from the horizontal positive x axis, the rope parallel the x axis. The coefficient of friction is .4, and the box accelerates up the ramp at an acceleration of 1.5 m/s^2. The box starts at rest.
I calculated the tension of the rope to be 756.155N, the normal force to be 525.506N, and the friction force to be 210.202N. The weight force is (9.8 m/s^2)(70kg)
1. How much work does each force perform on the box while the box moves 5 meters?
2. What is the net work done on the box?
3. What is the final velocity of the box, using the equation of work energy theorem?
