Answer:
(A) 0.3488 rad/sec
(B) 124.246 m
Explanation:
We have given car completes one revolution in 18 sec'
So time period T= 18 sec
Tangential speed v = 43.4 m/sec
(A) Angular velocity is given by [tex]\omega =\frac{2\pi }{T}=\frac{2\times 3.14}{18}=0.3488rad/sec[/tex]
(B) Tangential velocity is given v = 43.4 m /sec
We know that [tex]v=\omega r[/tex]
[tex]r=\frac{v}{\omega }=\frac{43.4}{0.3488}=124.426m[/tex]
