An outfielder catches 3 ft above the ground. How far has the ball traveled horizontally when the outfielder catches it.

**Jai**, Thursday, October 20, 2011 at 9:52pmto do this, we substitute h = 3 to the equation and solve for x:

h = -0.005x^2 + x + 3

3 = -0.005x^2 + x + 3

0 = -0.005x^2 + x

0 = x(-0.005x + 1)

x = 0 (this is extraneous)

x = 1/0.005 = 200 ft

hope this helps~ :)
