2*pi*r=565.484 time taken =565.484/25=22.6194sec so $\omega$=2*pi/22.6194=0.2831rad/sec

:)

or V=r*omega omega =V/r

That's the route I went @Algebraic!

6. 3psilon Group Title

But I got a small number , how do i convert it into radians

7. Aperogalics Group Title

multiply it with (pi/180) which converts it into radians:)

look at it this way... it's only going 25 m/s ... it's going to take a while to go around the circle once... 2pi/.2777777777 in fact, is how long one complete rev. will take...

@aperogalics showed that explicitly...

ohh okay okay ! Thank you @Algebraic!
