5. A piano of mass 200 kg has a starting (downward) velocity of 2 m/s at the top of an incline. The coefficient of kinetic friction is 0.2. a) Determine the total mechanical energy of the piano at the top of the incline. Use the ground as h=0 for gravitational potential energy. b) Determine the work done by friction as the piano slides. to the bottom of the incline. (Hint: draw a component FBD first!) 0=30⁰ d) Determine the total energy of the piano at the bottom of the incline. D=3m c) Describe EXACTLY what happened to the energy that you calculated in the previous part. e) Using mechanical energy, determine the velocity of the piano as it reaches the bottom of the incline.
