Solve the problem. -A person at the top of a 600 foot tall building drops a yellow ball. The height of the yellow ball is given by the equation h = -16t2 + 600 where h is measured in feet and t is the number of seconds since the yellow ball was Dropped. A second person, in the same building but on a lower floor that is 408 feet from the ground, drops a White ball 2 seconds after the yellow ball was dropped. The height of the white ball is given by the equation H = -16(t - 2)2 + 408 where h is measured in feet and t is the number of seconds since the yellow ball was Dropped. Find the time that the balls are the same distance above the ground and find this distance.
