Maybe the step response equation?
The Attempt at a Solution
I don't really understand the difference between a and b, but he said part a was supposed to be quite easy. Is a just:
mx'' = -k(x-y) - c(x' - y')
or something along those lines...
Okay, maybe it's best to do the last two bits in reverse order;
if the tangential acceleration is 18m/s^2, and the radius is 1m, is the angular acceleration also 18 radians/s^2?
Then is the moment: angular acceleration * the moment about the hip?
And that's the final answer?

The Attempt at a Solution
Okay, so I think the moment about CM is just m*0.24^2, but after that, I'm less sure.
Is the moment about the hip just...
