Which equation would best help solve the following problem?

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



–16t² + 20t + 1.2 = 0


–4.9t² + 20t + 1.2 = 0


–4.9t² + 20t = 1.2


–4.9t²+ 1.2t + 20 = 0
