Shooting an arrow over a wall |
2007-12-11 |
|
Amy pose la question :
The path of a large arrow fired from a non
torsion catapult can be modeled by y=-0.0044x^2 + 1.68x, where x is the distance the
arrow travelled (in yards) and y is the height of the arrow (in yards). Given the height of
a castle wall, find the safest distance from the wall to launch an arrow over a 120 yard-high wall.
