A cruise ship with a mass of 1.13 ✕ 107 kg strikes a pier at a speed of 0.712 m/s. It comes to rest 6.19 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest. Assume the ship moves in the positive direction. Indicate the direction with the sign of your answer.)
