A man can throw a ball a maximum horizontal distance of 175 m. The acceleration of gravity is 9.8 m/s^2. How far can he throw the same ball vertically upward with the same initial speed?

  • Physics - ,

    The range of an object thrown at the optimum angle (45 degrees) is
    R = Vo^2/g.

    The highest altitude obtained by an object thrown vertically upward is
    H = Vo^2/(2g)

    So he can throw it up half as far, or
    175/2 = 87.5 m upwards.

    Thanks helped tons:)
