A ride in an amusement park consists of a rotating arm AB that has an angular acceleration of a AB = 2 rad/s² when wAB = 3 rad/s at the instant shown. Also at this instant the car mounted at the end of the arm has an angular acceleration of a = {-0.6 k} rad/s² and angular velocity of w' = {-1.5 k} rad/s measured relative to the arm. Suppose that a = 10 ft and r = 2 ft . (Figure 1)
