In a truck-loading station at a post office, a small0.48 kg package is released from rest at point A on atrack that is 1/4 of a circle with radius 2.2 m (asshown in the below Figure). The size of the packageis much less than 2.2 m, so the package can betreated as a particle. It slides down the track andreaches point B with a speed of 3.5 m/s. From pointB, it slides on a level surface a distance of 4.9 m topoint C, where it comes to rest.mARKBd(a) How much work (in J) is done on the package byfriction as it slides down the circular arc from A to B?(b) What is the coefficient of kinetic friction on thehorizontal surface?

K-loading station at a post office, a small 3 kg package is released from rest at point A on a k that is 1/4 of a circle with radius 2.2 m (as wn in the below Figure). The size of the package uch less than 2.2 m, so the package can be ted as a particle. It slides down the track and ches point B with a speed of 3.5 m/s. From point slides on a level surface a distance of 4.9 m to t C, where it comes to rest. m
