Question

If a ball is thrown directly upward with a velocity of 34 ft/s, its height (in feet) after t seconds is given by y = 34t − 16t2. What is the maximum height attained by the ball? (Round your answer to the nearest whole number.)

Answer 1

1.0625ft

Answer 2

or 17/16

Answer 3

so 1 is the answer

Answer 4

18.0625, so 18. you found the distance the ball travelled from the starting point, not it's height

Answer 5

you need to substitute that value. Actually, you found the time it took to reach that height

Answer 6

very true. my bad
