Question

Maria releases a javelin 1.5 meters above the ground with an initial vertical velocity of 22 meters per second. How long will it take the javelin to hit the ground?

Answer 1

The javelin will hit the ground 14.66 or 15 seconds upon Maria's release from the said distance. The computation are as follows: 

time = distance/speed (d/m)
time = 22 meters/second / 1.5 meters 
time = 14.66 seconds or 15 seconds
