Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

This question came up on my homework and I am having a lot of trouble with it. I know how to answer the first part (part a) through antidifferentiation but after that the two parts b and c are very unfamiliar and I have no idea where to start. Any tips?
