###### FREE Expert Solution

This problem deals with the relationship between angular acceleration, radial/centripetal acceleration, and tangential acceleration.

We'll also need to apply rotational kinematics because radial/centripetal acceleration depends on angular velocity.

Tangential acceleration:

$\overline{){{\mathbf{a}}}_{{\mathbf{t}}}{\mathbf{=}}{\mathbf{r}}{\mathbf{\alpha }}}$

$\overline{){{\mathbf{a}}}_{{\mathbf{c}}}{\mathbf{=}}\frac{{\mathbf{v}}^{\mathbf{2}}}{\mathbf{r}}{\mathbf{=}}{\mathbf{r}}{{\mathbf{\omega }}}^{{\mathbf{2}}}}$ ###### Problem Details
