A ball swings counterclockwise in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, its resultant acceleration is a = (-22.5i + 20.2j) m/s2 , where i is the unit vector along the horizontal direction (you can treat it as pointing to the right), and j is the unit vector along the vertical direction (you can treat it as pointing upward).
For that instant,
(i) determine the magnitude of its centripetal acceleration in m/s2
(ii) determine the speed of the ball in in m/s
(iii) determine the velocity of the ball in m/s, i and j.
