Boy kicks a football with an initial velocity of 28.0 m/s at an angle of 60.0° above the horizontal. What is the highest elevation reached by the football in its trajectory?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
