Which equation would best 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
