A.) The time at which the rock lands
B.) How far horizontally from the bridge the rock lands
C.) The velocity of the rock (magnitude and direction) just before it lands. (magnitude)
D.) Direction: Give your answer in degrees. If you think the answer is "20 degrees down from the positive x-axis", you would enter "-20" (note the negative sign!)
