bch2014 Posted December 11, 2012 Share Posted December 11, 2012 "A rocket, rising vertically, is tracked by a radar station that is on the ground 5 miles from the launch pad. How fast is the rocket rising when it is 4 miles high and its distance from the radar station is increasing at a rate of 2000 mi/hr?" This is for my Calculus AB AP class, so please try and keep the explanation relatively simple for a noob like me. But any help is welcomed ! My teacher has been having us find the derivatives of each Component if you will (X, Y, Hypotenuse) if possible just leaving one that you have to solve for. But, when I try, I can only find one of the derivatives! Link to comment Share on other sites More sharing options...
isohume Posted December 11, 2012 Share Posted December 11, 2012 Ha, we had to do our own homework. You can do the same. Just keep plugging away at it. Link to comment Share on other sites More sharing options...

heavy_wx Posted December 11, 2012 Share Posted December 11, 2012 The first thing you should do is draw a diagram based on the given information with the axes labeled. Then, think about how the information given can be related to what you need to solve for via an algebraic equation and its derivative. Link to comment Share on other sites More sharing options...
