There were two basketballs with a piece of colored tape that were released from the window of a tall building. These two were identical except for their colors (one is green and the other is red). The red one is allowed to fall straight down, while the green one is thrown horizontally from the window. Which one hits the level ground below first when not involving air resistance? a. Both hit the ground at the same time b. One with red tape hits first c. One with green tape hits first d. It depends on how fast the green one is thrown horizontally e. It depends on the time of day when the experiment is done
