If one revolution takes 30 seconds, then the wheel is moving at

radians per second.

If the diameter of the wheel is 40 meters, then its radius is 20 meters and a point on the outside of the wheel is changing height at a rate of



meters per second relative to the centre of the circle, so the height function with respect to time is:
