uniform circular motion

AIEEE Preparation › Mechanics questions › uniform circular motion

A ball swings in a vertical circle at the end of a rope 1.5 m long. when the ball is 36.9Â° past the lowest point on its way up, its total acceleration is =( -22.5 i + 20.2 j).at that instant find the magnitude of radial acceleration of the ball.
ans = 29.7 m/s²
plz explain along with the answer
