A box of mass 18.3 kg with an initial velocity of 1.88 m/s slides down a plane, inclined at 28◦ with respect to the horizontal. The coefficient of kinetic friction is 0.77. The box stops after sliding a distance x. How far does the box slide? The acceleration due to gravity is 9.8 m/s 2 . The positive x-direction is down the plane. Answer in units of m.

Part B: What is the the work done by friction? Answer in units of J.

Part C: What is the work done by the normal force? Answer in units of J.

Part D: What is the magnitude of the work done by gravity? Answer in units of J.

Part E: What is the magnitude of the instantaneous power generated by friction half way between the initial and final positions? Answer in units of W.

Part F: What is the magnitude of the average power generated by friction from start to stop? Answer in units of W.
