# Homework Help: Applying physics to calculus

Forgive me if this is deemed a "homework question", b/c it kinda is, but I'm thinking about it a little differently...

It's a 3 dimensional calc. III problem, that I've broken down to this: Essentially there's an "enemy ship" traveling in a straight line at a constant velocity. I'm stationed at the origin and I want to fire at the ship (I know the speed the missle will fire at). So how do I determine at what angle to fire the missle so that it hits the moving target? I know it really boils down to a simple physics equation that I should remember from a million years ago..but, I don't... HELP!

### Integral

Staff Emeritus
it is a time problem, find equations in terms of time which describe the path taken by the projectile and one which describes the ships path. Find the point they arrive at at the same time.

Exactly...how do I find these time equations? Would they be parametric? Would they be based off of some simple physics equations that I'm just missing?:yuck:
