During a move, Kate and Lou have to push Kate's 80-kg stove up a rough loading ramp, pitched at an angle of 10°, to get it into a truck. They push it along the horizontal floor to pick up speed and give it one last push at the bottom of the ramp, hoping for the best. Unfortunately, the stove stops short and then slides down the ramp, sending them leaping to the side.

(a) If the stove has a speed of 3.0 m/s at the bottom of the ramp, and a speed of 0.8 m/s when it is 2 m up the ramp, what is the maximum height reached by the stove?

(b) What is the stove's speed when it passes the 2-m spot again?

(c) What is the energy dissipated by friction during the complete round trip back to the bottom of the ramp?
