Question

Vernon Wells hits a baseball that travels for 142m before it lands. The flight of the ball can be modelled by a quadratic function in which x is the horizontal distance the ball has travelled away from Vernon, and h(x) is the height of the ball at that distance.

Assume that the ball was between 0.6m and 1.5 m above the ground when it was hit. What would h(142) be?

Answer 1

(a) Since most balls are hit at a fairly low trajectory, I'd say that since the max height of the ball occurs at roughly 71 meters, that might be a good estimate for the height of the ball at that point.
