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. When Θ = 20.0 degrees, the speed of the object is 8.00 m/s. At this instant, discover
a) The tension in the string
b) Total acceleration
c) The tangential and radial components of acceleration
d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up? Why?
