Question

A runner starts from a point $A$ and travels in a straight line. Her velocity, $v$ m/s, at time $t$ seconds after passing $A$ is given by $v = 2t - \frac{1}{3}t^2$. Find the initial velocity Find the values of $t$ when the runner is instantaneously at rest.

Accepted Answer

(a) $0\text{ m s}^{-1}$; (b) $t=0,6\text{ s}$
