Awheel is rotating at a rate of 2.0 rev every 3.0s. through what angle, in radian , does the wheel rotate in 1.0s?

Explanation:

First of all, let's convert 2.0 rev into radians:

This means that the angular speed of the wheel is

The angle through which the wheel rotates in a time t is given by

And substituting t=1.0 s, we find
