Compute the magnitude of the radial acceleration of a point on its rim at the start.

Explanation / Answer

A)
atan = r* angular acceleration
         = 0.4 m * 0.9 rad/s^2
         = 0.36 m/s^2

B)
Radial acceleration = v^2/r
                                   = 0^2/0.4
                                    = 0 m/s^2
