A body is moving in a straight line which passes through a fixed point 'O'. The displacement, 's' metres, of the body from 'O' at time 't' seconds is given by:
s = t³ + 4t² - 5t
a) Find an expression for the velocity, v m/s, at time 't' seconds.
b) Find the acceleration after 2 seconds.
I really have no idea what this question is about!
