Electric drill starts from rest and rotates

Reference no: EM13663227

An electric drill starts from rest and rotates by a constant angular acceleration. After the drill has rotated through a certain angle, the magnitude of the centripetal acceleration of a point on the drill is twice the magnitude of the tangential acceleration. What is the angle?
