A cruise ship with a mass of 1.00 × 10 7 kg strikes a pier at a speed of 0.750 m/s. It comes to rest 6.00 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest.)

A cruise ship with a mass of 1.00 × 10 7 kg strikes a pier at a speed of 0.750 m/s. It comes to rest 6.00 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest.)

To determine

The average force on the pier.

Explanation of Solution

Given:

Mass of cruise ship m=1×107kg

Initial Speed of ship u=0.75m/s

Final speed of ship v=0

Distance taken by the ship to come at rest d=6m

Calculation:s

We know the velocity acceleration equations

  v2=u22as.........(1)

  a=u22s

  v=uat.............(2)

  (a=veretardation)
