Q1. One end of a cord is fixed and a small 0.500kg object is attached to the other end, where it swings in a section of a vertical circle of radius 2.00 m, When angle=20.0 degrees, the speed of an object is 8.00 m/s. At this instant. Find out-

(a) The tension in the string.

(b) The tangential and radial components of acceleration, and

(d) Is your reply changed if the objects are swinging down toward its lowest point instead of swinging up?
