A 2.3 kg box, starting from rest, is pushed up a ramp by a 10 N force parallel to the ramp. The ramp is 2.0 m long and tilted at 17. The speed of the box at the top of the ramp is 0.80 m/s. 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 the system? c. What is the change _Ug in the gravitational potential energy of the system? d. What is the change _Eth in the thermal energy of the system?
