A ball swings in a vertical circle at the end of a rope 1.50 m long. When the ball is 37.1° past the lowest point on its way up, its total acceleration is (-22.5 i + 20.2 j) m/s2.
(a) At that instant, sketch a vector diagram showing the components of its acceleration. (No points for this, but it will help solve the problem!)
(b) Determine the magnitude of its radial acceleration.
???? m/s2
(c) Determine the speed and velocity of the ball.
