Question:

A wheel centered at the origin and of radius 10 centimeters is rotating counter-clock-wise at a rate of 4 revolutions per second. A point P on the rim of the wheel is at position (10.0) at time t = 0.
(a) What are the coordinates of Pat times t = 1, 2, 3?
(b) At what time does the point P first return to the starting position (10.0)?
