Question

A submarine is following a horizontal 500-m circle at 20 knots (1 knot = 1.852 km/hr). At the instant when it is aligned with the horizontal and vertical directions, it is rolling at 0.5 rad/s and pitching at 0.1 rad/s, as shown. Both rates are maxima at this instant. Determine the velocity and acceleration of the tip of the periscope, which is being extended at the constant rate of 10 m/s.

10 m/s 12 m Roll 500 m Pitch
