Let z = z(t) and y = y(t) (where tis the variable of time) be the horizontal and vertical positions of a particle moving (in the zy-plane) along a circle (centered at the origin with radius R) counterclockwise. Assume the positive directions (for the particle's horizontal and vertical positions) as they are in the zyplane and the reference point (of the position functions) is the (0,0). As it reaches the point (a, B) (where a < 0,B > 0), the particle's vertical position is changing at a rate of u, #0.
