Shaw's leg segment is rotating with a constant angular velocity of 11.7 rad/s about his knee joint. The origin of reference frame is at his knee joint. At a specific instant in time, the coordinates of his ankle are -0.2,0.21 m. At that instant, what is the vertical acceleration (m/s2) of the ankle?
