what is common to the variation in the range and the hieght of a projectile. I'm thinking of horizontal acceleration pls what do u think

  • Elementary mechanics -

    My answer is the Rise Time or time to reach max. height.

    R = Vo*cosA * (Tr+Tf)
    Tr = Tf. Therefore,
    R = Vo*cosA * 2Tr.

    Tr = Rise time.
    Tf = Fall time.
    Vo*cosA = Hor. component of initial
    velocity.
