Two golf balls are thrown with the same speed off the top of a large bridge at the same
time. Ball A is thrown straight downward, and Ball B is thrown horizontally off the
bridge. Which ball hits the ground first?

  • physics -

    The 1st ball
    h=v₀t₁+gt₁²/2

    The 2nd ball
    x=v₀t₂
    h = gt₂²/2

    t₁<t₂
