Homework Help: Impulse Energy relationship

  1. May 5, 2004 #1
    I am trying to calculate the height that a rocket engine will fly, by deriving the equation Gravitational potential energy(gPe)=FXH, where F is the weight of the engine and h is the vertical distance. The gPe at the rockets highest point must equal the chemical potential energy that the engine possess. From this I can find the height. My problem is that I have do not know how much chemical potential energy the engine possess, but I know what its impulse is. If the engine produces 5.00NXS of impulse what energy does it have? Can impulse(NXS) be converted to energy(NXM)? I hope this post is clear. Thanks for your help.
