Homework Help: Angled Projectiles

  1. Oct 7, 2009 #1
    The question is A rocket has the range of 300 km and the max. height of 100km. Determine the initial velocity. How do I figure this out?

    I know you have to find out vertical and horizontal componets but I don't think I know how to do that.

    No it doesn't it, its part of your suppose to figure out.

    when you are figuring out time do you use d=Vi(t)+1/2At^2 but alter it to find time?

    Write down the relevant equations for vertical component and horizontal component of velocity, time of flight, maximum height and maximum range.
