An arrow is shot with an initial upward velocity of 100 feet per second from a height of 5 feet above the ground. The equation h= - 16t^2+100t+5 models the height in feet t seconds after the arrow is shot. After the arrow passes its maximum height, it comes down and hits a target that was placed 20 feet above the ground. About how long after the arrow was shot does it hit its intended target?
