What will be the answer for 4b? Please explain

4. Write a quadratic equation to model the height of the falling ball in feet, H, after x seconds. (Hint: H = ax + bx + c, where a, b, and c are defined as indicated below. Note: The starting speed (b) will be zero since the ball is simply dropped and not thrown.) a. Acceleration from #3 part a) = -32 t / sec a = - 16 = 1/2 . acceleration (due to gravity) (feet / sec2) b = 0 = starting speed (feet / sec) C = 500 = starting height (feet) Quadratic Equation: H = -16X +0x +500 b. How long will it take for the ball to hit the ground? Find the number of seconds, x, that will mak the height, H = 0
