Change of Angle of Boat Firing Torpedo
Question
A torpedo boat with a displacement of 60 long tons is moving at 18 knots when it fires at 300-lb torpedo horizontally with the launch tube at the 30° angle shown. If the torpedo bas a velocity relative to the boat of 20 ft/sec as it leaves the tube, determine the momentary reduction ∆v in forward speed of the boat. Recall that 1 knot = 1.688 ft/sec and 1 long ton = 2240 lb. Solve the problem also by referring the motion to a coordinate system moving with the initial speed of the boat.
Summary
The question belongs to Mechanical Engineering and the question is about calculating the speed of the boat after it launches a torpedo at a 30° angle. The momentary reduction in speed of the boat needs to be calculated. The calculation has been given in the solution in detail.

WHAT OUR STUDENTS SAY
The management case study was based on a factory in Napier, which I am sure no US based or UK based assignment experts could have solved. I searched online for management assignment experts from New Zealand but was not being able to narrow down on one. Luckily, then I bumped into TheReliableTutor and found out that the management assignment experts are actually from New Zealand. The case study went well and so did the other management assignment solutions, for which I took help from them again.

The earlier service I was using only used to provide me with the codes for the Programming assignment help requested from them. At TheReliableTutor the online Singapore Programming tutors provide notes along with the codes which have helped me understand how the code actually works and explain it to the professor too. It has now become a habit with me too.

I was really worried about my nursing ethics case study assignment which was related to the issue of nurses sharing their photos along with their patients’ in the internet. I was confused about what stand to take when I came across HwA. That was the first work they did for me. From there it only got better. I am now thinking of doing my MN and will definitely seek their help for that.
Danny Taylor Student
I got stuck with my supply chain assignment when I looked online for help. HwA was the only Australian site which responded almost instantly. When the solution also reached my email just on the next day, I was thrilled. The answers were correct and became a fan. From there on I kept on taking help from them.
Hannah Waugh Student
I was badly stuck with an argumentative term paper writing assignment when I started searching for help on the net. I never thought that I will get any sort of specialized help for the Australian universities and when HwA promised to deliver that, I thought why not? Then I chatted with the expert and she helped me out by writing and excellent term paper which helped me get great grades.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
