Homework Help: Stone thrown from a balloon

  1. Mar 24, 2010 #1
    1. The problem statement, all variables and given/known data
    If a stone is dropped over the side of a hot air balloon that is rising at 3 m/s and it strikes the ground 1.5s later, from what height above the ground was the stone dropped

    Would V1 be 3 m/s or 0.. I'm really confused.

    Both the hot air balloon and the stone will have the same initial velocity, so v1 would be 3 m/s.

    Make sure you know your trajectory equations!
