    1. The problem statement, all variables and given/known data
    Calculate any or all of the following: horizontal velocity, initial vertical speed, angular launch speed, launch angle, and maximum height all for an object with a mass of 7.3g that is projected 24.5m.


    2. Relevant equations



    3. The attempt at a solution
    V=d/t V=24.5/7.3 V=15.031

    Your solution is incorrect. What do the symbols in the equation v=d/t represent?

    Pardon me if I am wrong but knowing mass in this case is useless or is it time?

    If we are ignoring drag (which I am assuming that we are), then you are indeed correct. The mass of the object is superfluous in this case.
