- Homework Statement:
- Calculate the magnitude of the velocity at point from a given equation a(t)

- Relevant Equations:
- a(t) = r^3(t)

These questions keep appearing in my past-papers and yet at no point in the course notes can I find a worked solution. Unfortunately I'm not sure where to start. My initial thoughts were regarding getting an equation using known values but w.r.t. to t and integrating for v, but like I said I have nothing to go off apart from a final answer. Any help would be greatly appreciated.

The solution for the problem included is v = 2.74m/s
