Answer:

Explanation:
First, the instant associated to the angular displacement is:

Roots of the second-order polynomial are:

Only the first root is physically reasonable.
The angular velocity is obtained by deriving the angular displacement function:


The angular acceleration is obtained by deriving the previous function:

The resultant linear acceleration on the rim of the disk is:
