Question

How do you find the horizontal distance the ball traveled? I have the first part down its same problem but instead its y=-32/20^2 X^2+x+5

Answer 1

A ball is thrown across a playing field from a height of h = 5 ft above the ground at an angle of 45° to the horizontal at the speed of 20 ft/s. It can be deduced from physical principles that the path of the ball is modeled by the function
y = − 32/(20)^2 x^2 + x + 5
where x is the distance in feet that the ball has traveled horizontally.

Find the horizontal distance the ball has traveled when it hits the ground. (Round your answer to one decimal place.)
