Answer:
(a) Angular speed will be 0.2512 rad/sec
(b) Radius will be 213.375 m
Explanation:
We have given time to complete 1 lap = 25 sec
We know that 1 lap = [tex]2\pi[/tex] radian
(a) So angular speed [tex]=\frac{2\pi }{25}=\frac{2\times 3.14}{25}=0.2512rad/sec[/tex]
(B) Tangential velocity is given as v = 53.6 m/sec
We know that tangential velocity is given by
[tex]v=\omega r[/tex]
So radius [tex]r=\frac{v}{\omega }=\frac{53.6}{0.2512}=213.375m[/tex]
