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 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.
