##### While working on a high-rise building, a construction worker drops a bolt from $320 \mathrm{m}$ above the ground. After $t$ seconds, the bolt has fallen a distance of $s$ metres, where $s(t)=5 t^{2}, 0 \leq t \leq 8 .$ The function that gives the height of the bolt above ground at time $t$ is $R(t)=320-5 t^{2} .$ Use this function to determine the velocity of the bolt at $t=2$.
