What is the Angular Speed of a Car Wheel?

[chowyo123]

A car wheel turns through 277 degrees in 10.7 s. Calculate the angular speed of the wheel.

Well, i know the Angular Accelereartion is equal to the change in angular velocity divided by the time required to make that change.

So should i first convert 277 degrees to radians?.. which is 277/180pie. I guess I'm not even sure where to begin right now.

you're forgetting a simple equation:

$$\omega = \Theta / t$$

Yes,as andrewchang said. All you are finding is a speed, which is equivalent to s = d / t (speed equals distance divided by time). In your case, however, you are using degrees.

Hope this helped.

wow, thanks. That should help me greatly.
