Homework Help: Projectile motion

  1. Sep 23, 2005 #1
    This problem seems to confuse me! If someone helps me with this problem I'll be so grateful!!

    An Archer fish shoots at a target 2m away, at an angle of 30 degrees above the horizontal. With what velocity must the water stream be launched if it is not to drop mote than 3cm vertically on its path to the target?

    Deal with x- and y-directions separately.
    Hint: x-speed is constant.
