A cyclist goes once around a circular track of diameter $105$ metre in $5$ minutes. Calculate his speed.
A cyclist goes once around a circular track of diameter $105$ metre in $5$ minutes. Calculate his speed.
Given $D=105 m , R =\frac{105}{2}=52.5 m$
$t=5 \times 60=300 s$
Now, speed $=\frac{\text { distance }}{\text { time }}=\frac{2 \times 3.14 \times 52.5}{300}$
$=1.1 m s ^{-1}$
