Question
![Part A
In a truck-loading station at a post office, a small
0.200 kg package is released from rest at point A on a
track that is one-quarter of a circle with radius 1.60 m
(Figure 1). The size of the package is much less than
1.60 m, so the package can be treated as a particle. It
sides down the track and reaches point B with a speed
of 4.40 m/s. From point B, it slides on a level surface a
distance of 3.00 m to point C, where it comes to rest.
What is the coefficient of kinetic friction on the horizontal surface?
