math problem help please!?

Question

A wheel of radius 14 inches is rotating about an axle and the angular speed of a ray from the center of the wheel to a point P on the rim is 7pi/4 radians per second. If P initially has coordinates (14,0) and the center of the wheel is at the origin, find the position (x,y) of P after t seconds.

Answer 1

In polar coordinates, its position will be (14, 7pit/4).

In cartesian coordinates we have
(14cos(7pit/4), 14sin(7pit/4))
