Have gotten help figuring these out, but unsure how to set up the last one. Thanks for any help or direction The runway at Edwards Air Force base is 15,000 feet long. What is the maximum velocity the shuttle can have at touchdown and still stop on the runway? |

It's not that, Joe; seems to me this is like you just learned how to ride a tricycle, and now want to pilot a supersonic jet...get my drift? |

Joe, here's the situation (as I see it): if you had been introduced to that problem in a classroom, the teacher would have explained (using chalk and blackboard, something we can't use here!) how to solve the problem; then you would try to solve it, and if you were not able to get the given solution, then you would go to a help site (such as this one), posted the problem and show where you're stuck. I don't think you should pick problems at random and post them at help sites. I may be wrong, so I'll let someone else here step in and give me hell if so. OK? |

Yeah, I understand I tried to be in a traditional but it was/is to fast paced for me. oh okay I am just stuck on where I would but if I am even close the -6, and the 1.5 as I get at least that the 15000= but where to plug in the other numbers is where I am lost... oh I am sorry That I made it appear that I was just randomly posting problems ![]() but I understand if it's better for me to hopefully get help with someone in person, rather than here with this problem, thanks for at least talking to me and telling me to move on ![]() Last edited by GIjoefan1976; May 19th, 2017 at 02:18 PM. | |

You already have that d= 0.5v+ v^2/24. If the runway is 15000 feet long, then d can be anything less than that. The largest d can be is 15000 so the question is just asking you to solve the quadratic equation v^2/24+ 0.5v= 15000.
