I'm a little stuck on this:(adsbygoogle = window.adsbygoogle || []).push({});

Suppose that the acceleration of a train during the interval of time from t=2 s to t=4 s is a=2t m/s^2, and at t=2 s its velocity is 180km/h

Using formulas: Velocity v=ds/dt and acceleration a =dv/dt, determine:

(a) the train’s velocity at t=4 s,

and;

(b) the displacement (change in position) from time t=2 s to t= 4 s

I should really be able to do this but for some reason my mind has frozen so I was hoping for some help or some nudges in the right direction!

Thanks in advance!
