Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 109 feet, and ball 2 is droppe

Natalija [7]

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

$t^2=\dfrac{109}{16}\\$

$t=\sqrt{\dfrac{109}{16}}$

$t=\dfrac{\sqrt{109}}{2}$

t = 5.22
