Tania releases a javelin 1.2 m above the ground with an initial vertical velocity of 20 m/s. How long will it take the javelin to hit the ground?

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

im pretty sure its

(8,15)

step-by-step explanation:

the first option is the answer.
