If you can throw a ball vertically upward to a height h = 30.1 m, what is the maximum horizontal range over which you can throw the same ball, assuming you throw it at the same initial speed

  • Physics - ,

    Twice as far.
    Here's the reason
    The maximum height when you throw vertically is V^2/2g.
    (That is easily proven using conservation of energy)
    The RANGE X at any angle A is
    2 sinAcosA/V^2/g, and the maximum range is obtainec at a A = 45 degree angle, for which
    Xmax = V^2/g
