Artillery gun projectile motion problem

  1. Nov 2, 2003 #1
    im having a hard time on this physics problem. i would appreciate it if you would provide the full solutions for this problem. thx a lot. hint : projectile motion

    A artillery gun can fire shells at 100 m/s. It is mounted on top of a 300 m high hill. AT what 2 angles could it be aimed above the horizontal in order to hit a target located 500 m away? Show all your work.

    If you have had a hard time on it- does that mean you've already done quite a lot of work on it? How about telling us what you have already tried.

    In particular, you certainly should have written down the formulas you have available to use. What is the formula for the height of the projectile in a problem like this? What are the initial and final heights? What is the formula for horizontal motion?
