A ball swings in a vertical circle at the end of a rope 1.30 m long. When the ball is 37.3 ° past the lowest point on its way up, its total acceleration is (âˆ'22.5 i + 20.2 j ) m/s2. For that instant, do the following.
(a) Sketch a vector diagram showing the components of its acceleration.
(b) Determine the magnitude of its radial acceleration.
(c) Determine the speed of the ball.
(d) Determine the velocity of the ball - Give the magnitude and direction.
