## Kagome_gurl8 2 years ago The function y=-16t^2+384 models the height y in feet of a stone t seconds after it is dropped from the edge of a vertical cliff. How long will it take the stone to hit the ground? Round to the nearest hundredth of a second.

1. CalebBeavers

Plug in 0 for y and then solve for t 0=-16t^2+384

2. Kagome_gurl8

this is my answer 6.93 seconds is it correct?

3. CalebBeavers

I got 4.90...

4. CalebBeavers

16t^2=384 t^2=24 $t=\sqrt{24}$
