A ball, which is initially at rest, starts rotating around a fixed point. The ball has a constant angular acceleration. You need to know that the radial acceleration of the ball arad is proportional to ball's angular displacement θ.

Find the angular displacement of the ball if its resultant acceleration makes an angle of 35.3 ∘ with the radial direction?
