One end of a cord is fixed and a small 0.500-kg object is attached to the
other end, where it swings in a section of a vertical circle of radius 2.00 m
as shown in the Figure. When θ = 20.0°, the speed of the object is 8.00
m/s. At this instant, find (a) the tension in the string, (b) the tangential and
radial components of acceleration, and (c) the total acceleration.
