Question: A 2 . 3 kg box, starting from rest, is pushed up a ramp by a a 1 0 N force parallel to the ramp.

A 2.3 kg box, starting from rest, is pushed up a ramp by a a10 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 is 0.80 m/s.(a) How much work is done by the force on the system (box + ramp + Earth)?(b) What is the change in kinetic energy of the system?
(c) What is the change in gravitational potential energy of the system?
(d) What is the change in thermal energy of the system?
