A cruise ship with a mass of $1.00 \times 10^{7} \mathrm{kg}$ strikes a pier at a speed of 0.750 $\mathrm{m} / \mathrm{s}$ . It comes to rest 6.00 $\mathrm{m}$ 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.)

Okay, so here's the cruise has a moss off to do far. Seven keys on what it had It strikes a pyre is beautiful your prints certain time just per second. So this you is equality General point 75 meters per second. So it comes to arrest 16. It's nature, right? So it comes to arrest six minutes, six meters majors The distance we travel cities six meters damaging the sheep. The fire on the tugboat captain's finances so integrated every force exerted in the fire. You know the concept of impulse. So every sports f is it? It worked using the concept of peoples. Well, to do that, what we can do is force is God. He is equal to the impulse upon time. Chicken right impulse off time chicken Now impose here He's what must into change in velocity. So boss instated are seven times change and thirsty is only zero point Fight, right? Yeah. Now what is the time? So from immigration. Uh oh. You know what we can? What we can do here? He's instead of doing this, what we can do is we can break this impulse into two terms, right? So impulse is in fact, mass times the chains in diversity of Wonder Team as you can right here. So what we can do is write this divinity as accelerations him into a no exercise can be written as from the question of motion can read him as these Corvinus C squared off twice s right. So here Must can read really mass into the bar. Seven in seven cities. Zero The final necessity. He's, you know, Sorry instead of Felicity, Finalist in zero Incentive Cities, 0.75 Esquire. So this divided Rivai two times six. That is child. So if you divide this all you get have to be This is that it's physical too. 4169 negative into 10 to the power five. All right, so we have I'm quitting the force on the completed the force on the pyre. All right, so on the fire, if you want. This is the force on the cruise ship, right, Because it is negative. Right? So we have We have only talking about the sheep here, right? So this is the force on the ship. So you the force of the ship is this myself on the Cruz is this mess on the fire movie. So equal and negative breaks on the fire that will be equal and negative. So negative minus four. Consistent is just lust for prince explained. Did you get the power? Five years. This is Ah, no, this came from because you didn't say get enough margin. That is the forces calling uppers. Okay, so we had only listened to this problem.
