A 0.2 kg object is released from rest at point A on a track that is one-quarter of a circle with radius 1.6 m, as shown in the figure. It slides down and reaches point B with a speed of 4.8 m/s. Then it slides on a level surface a distance of 3 m until it comes to rest at point C.
a) How much work is done by friction on the package at it slides down the circular track from A to B?
b) What is the coefficient of kinetic friction on the horizontal surface?
c) What average power is produced by friction as the object moved from B to C?
d) What instantaneous power is produced by friction at point B?
