A ball swings in a vertical circle at the end of a rope 1.50 mlong. When the ball is 36.9° past the lowest point on its wayup, its total acceleration is 1222.5 i^ 1 20.2 j^ 2 m/s2. For thatinstant,
(a) sketch a vector diagram showing the component sof its acceleration,
(b) determine the magnitude ofits radial acceleration, and
(c) determine the speed and velocity of the ball.
