Problem

A turntable of radius

0.15\,\text{m}

is rotating at

10\,\text{rad s}^{-1}

and is slowing down with a uniform angular deceleration of

2.0\,\text{rad s}^{-2}

. Determine the angle that the resultant linear acceleration of a point on the rim makes with the radius directed towards the centre at this instant.
