Under the action of its stern and starboard bow thrusters, the cruise ship has the velocity v_B = 1 m/s of its mass center B and angular velocity about a vertical axis. The velocity of B is constant, but the angular rate is decreasing at 0.5 deg/s². Person A is stationary on the dock. What velocity and acceleration of A are observed by a passenger fixed to and rotating with the ship? Treat the problem as two-dimensional.
