In a truck-loading station at a post office a small 0.2 kg package is released from rest at point A on a track that is one quarter of a circle with radius 1.6 m. a. If 1.372 J of work are done against friction as the package slides down the circular arc from A to B, what is the speed of the package when it reaches point B? b. If the package slides along the horizontal surface and comes to rest at point C, how much work was done by friction between points B & C? c. If the force of friction opposing the packages motion as it moves from point B to point C is 0.588 N, how far does the package slide before coming to rest at point C?
