I am having a problem with the problem:
A wheel of radius 1 meter rests on the x-axis with it's center on the y-axis. There is a spot on the rim at point (1,1). At time the wheel starts rolling on the x-axis towards positive infinity (to the right) at a rate of 1 radian per second. Find parametric equations describing the motion of
(a) The center of the wheel.
(b) The motion of the spot on the rim.
I think I have part a figured out. , as the center of the wheel will not go up or down and the arc length on a unit circle is the same as its measure in radians (please correct me if I am wrong)
For b I am guessing that I can describe y with , but I cannot figure out how to model x.
Please point out any points on which I am incorrect, and give any assistance you can.
