11/25
Step-by-step explanation:
Answer: 5.22 seconds
<u>Step-by-step explanation:</u>
t represents time and y represents the height.
Since we want to know when the ball hits the ground, find t when y = 0
Ball 1 starts at a height of 109 --> h = 109
0 = -16t² + 109
16t² = 109
![t^2=\dfrac{109}{16}\\](https://tex.z-dn.net/?f=t%5E2%3D%5Cdfrac%7B109%7D%7B16%7D%5C%5C)
![t=\sqrt{\dfrac{109}{16}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cdfrac%7B109%7D%7B16%7D%7D)
![t=\dfrac{\sqrt{109}}{2}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B%5Csqrt%7B109%7D%7D%7B2%7D)
t = 5.22
