(adsbygoogle = window.adsbygoogle || []).push({}); A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s^{2}Determine the time for the feather to fall to the surface of the moon.

So, I wrote my given:

d=1.4 m

a= 1.67 m/s^{2}

both initial and final velocity= 0

I know I am looking for time, but I have no idea what equation to use. I tried:

v_{f}= v_{i}+at , but I didn't get the right answer. The answer should be 1.29 s.

Any help would be much appreciated, please and thank you!:)
