a man throws a rock horizontally off a building with an initial velocity of 22.4 m/s. it hits the ground 91.6 m from the building. how tall is the building? (positive value)

  • physics -

    91.6 m / 22.4 m/s = 4.09s is the time it takes to hit the ground. Call it T.

    (1/2) g T^2 = height, H
    Solve that for H
