A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time a 1.00 s later. (c) If V0 is greater than some value Vmax, a value of the height of the building does not exist that allows both balls to hit the ground at the same time. Solve for Vmax. (d) If V0 is less than some value Vmin, a value of the height of the building does not exist that allows both balls to hit the ground at the same time. Solve for Vmin.
