Homework Help: Horizontal projectile Motion

  1. Jan 21, 2013 #1
    This is the problem word for word:
    A student throws a baseball at a large gong
    48 m away and hears the sound of the gong
    1.18893 s later. The speed of sound in air is
    330 m/s.
    What was the average speed of the baseball on its way to the gong? (For simplicity,
    assume its trajectory to be a straight line.)
    Answer in units of m/s.

    I don't need the answer. I'd really just like to be pointed in the right direction.
    Thanks so much.

    The first thing to do is to write down the relevant kinematic equations.
