16–145. A ride in an amusement park consists of a rotating arm AB having a constant angular velocity vAB = 2 rad>s point A and a car mounted at the end of the arm which has a constant angular velocity V' = {−0.5k} rad>s, measured relative to the arm. At the instant shown, determine the velocity and acceleration of the passenger at C.
16–146. A ride in an amusement park consists of a rotating arm AB that has an angular acceleration of aAB = 1 rad>s2 when vAB = 2 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 = {−0.6k} rad>s2 and angular velocity of V'
= {−0.5k} rad>s, measured relative to the arm. Determine the velocity and acceleration of the passenger C at this instant.
