Question

A particle travels in a straight line such that, $t$ seconds after passing a fixed point $O$, its displacement, $s$ metres is given by $s = 13t^{2} - 8t$. Find an expression for the velocity $v$ m/s, Find the velocity at $t = 5$s

Accepted Answer

(a) $v=26t-8\text{ m s}^{-1}$; (b) $122\text{ m s}^{-1}$
