*16–144. The cars on the amusement-park ride rotate around the axle at A with a constant angular velocity vA >f = 2 rad>s, measured relative to the frame AB.At the same time the frame rotates around the main axle support at B with a constant angular velocity vf = 1 rad>s. Determine the velocity and acceleration of the passenger at C at the instant shown.
16–147. If the slider block C is fixed to the disk that has a constant counterclockwise angular velocity of 4 rad>s, determine the angular velocity and angular acceleration of the slotted arm AB at the instant shown.
