I don't think so. it should be x(120). so x(24) for first part and then x(120-24) for the second piece right?

Well someone helped me come up with a piecewise function. which reads x(t) = (0m/s)t+1/2(1m/s^2)t^2 if 0≤t≤24 (24m/s)(t-24) if t≥24 However they could not really explain to me how they got that. They said something about equation of motion and constant acceleration. but we...

Velocity is 0 at t =0. my function is V(t) = .0033m/s^3 t^2. which then fails the velocity at 120 seconds. And when i start to change any of the coefficients it just gets worse. I have even tried it in this format v(t) = 3at^2-2bt

I have been working on this for a few days. The issue is not that it is hard to take the derivatives of the function i was given. The issue is that whenever i find a new equation to satisfy one criteria, it fails another.
