1. The problem statement, all variables and given/known data

A jet engine moves along an experimental track. Its psoition as a function of time is given by the equation x=At^2+B. A=2.10 m/s^2 and B=2.80 m. A)Determine the displacement of the engine during the time interval from t(sub1)=3.00s, to t(sub2)=5.00s. B)Determine the Avg. velocity during this time interval C.)Determine the magnitude of the instantaneous velocity at t=5.00s.

2. Relevant equations

3. The attempt at a solution

I cant even try to attempt this, I dont know calculus, and cannot do the derivatives for the Instantaneous velocity. I need A.)how to do the derivatives, and B) part C for this question

Thanks :-)
