Chapter 10, Problem 54(choose chapter or problem)
A 2.3 kg box, starting from rest, is pushed up a ramp by a10 N force parallel to the ramp. The ramp is 2.0 m long andtilted at 17. The speed of the box at the top of the ramp is0.80 mis. Consider the system to be the box + ramp + earth.a. How much work W does the force do on the system?b . What is the change !:;.K in the kinetic energy of thesystem?c. What is the change!:;. Ug in the gravitational potent.ial energyof the system?d. What is the change t:;.E,h in the thermal energy of the system?
