Legolas shoots a flaming arrow straight up into the air (from a distance of 2.6 meters from the ground) at 42 meters per second. The gravitational pull of the Earth is about 4.9 meters per second squared.
Which quadratic equation correctly models this situation, where h represents the height of the arrow after t seconds?
h=42t2+4.96t−2.6
h=2.6t2−42t−9.86
h=−4.9t2+42t+2.6
h=−9.86(t−42)(t+2.6)
1 answer
if you meant to type h=−4.9t^2+42t+2.6 , that would be it
