Homework Help: Projectile problem with no angles

  1. Sep 5, 2006 #1
    A projectile is fired horizontally from a gun that is 53.0 m above flat ground. The muzzle velocity is 235 m/s. How long does the projectile remain in the air?

    All of the practice problems in my book are given an angle to work with. For some reason I'm having a hard time starting this problem because I'm under the impression that I need to find an angle but I feel like I don't have enough information. Any help to point me in the right direction is greatly appreciated.

    you still have an initial angle. It is just 0 degrees from the horizontal axis.

    Which means it is falling out of "rest" downwards.
