Question

Eric has a treehouse 14ft above the ground. How long would it take a water balloon dropped from the treehouse to fall to the ground?

Answer 1

`14 ft =14xx0.3048=4.27 m`

The distance that body falls verticaly is `(g t^2)/2`

`(9.81 t^2)/2=4.27`

`t^2=4.27xx2/9.81=0.871`

`t=sqrt(0.871)=0.933 s`
