Question 1074428: A ball is thrown upward with an initial velocity of 40 feet per second
from ground level. The height of the ball, in feet, after t seconds is
given by h  16t
2  40t. At the same time, a balloon is rising at a
constant rate of 10 feet per second. Its height, in feet, after t seconds
is given by h  10t. Find the time it takes for the ball and the balloon
to reach the same height.
