One end of a cord is fixed and a small m = kg object is attached to the other end, where it swings in a section of a vertical circle of radius r = m as shown in Figure P6.18. When th = , the speed of the object is v = 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.
(d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up?
(e) Explain your answer to part (d).
