A uniform solid sphere of radius `r = ( R)/(5)` is placed on the inside surface of a hemisherical bowl with radius `R (= 5 r)`. The sphere is released from rest at an angle `theta = 37^@` to the vertical and rolls without slipping (Fig.) The angular speed of the sphere when it reaches the bottom of the bowl is.
