Aball is thrown across a playing field from a height of h = 3 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
x2 + x + 3
where x is the distance in feet that the ball has traveled horizontally.
(a) find the maximum height attained by the ball. (round your answer to three decimal places.)
incorrect: your answer is incorrect. ft
(b) find the horizontal distance the ball has traveled when it hits the ground. (round your answer to one decimal place.)
