The height of a ball that was batted into the air at 150 feet per second is a function of t, the time in seconds after the ball was hit. The height is determined by subtracting 15 times the square of t from 150 times t. Which equation can be used to find t when the ball is 300 feet high?

h = Vo*t + 0.5g*t^2.
150t - 16.2t^2 = 300 Ft.
