A small mass is stuck to a point on the rim of a rolling wheel(radius of r) .. which traces out a path called a cycloid. The position vector of this point is given by r(theta)= r(theta - sin theta)i +r(1-cos theta)j. For a wheel rolling with constant angular speed, Determine the velocity vector, the acceleration vector and verify the magnitude of the acceleration vector.
