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 
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 
from the ground, drops a white ball 
after the yellow ball was dropped. The height of the white ball is given by the equation
