A box with mass 0.0325 kg moves in a vertical circle that has a
radius of 0.600 m on the inside of a circular track. When the box
is at the bottom of its path, point A, the magnitude of the normal
force exerted on the box by the track has magnitude 3.75 N. When
the box reaches the top of its path, point B, the magnitude of the
normal force exerted on the box has magnitude 0.665 N.
