Question

Pete slid a domino off a bridge and it took 2.3 seconds to hit the Gully below how many feet did the domino fall

Answer 1

To solve this, we are going to use the distance of a free fallen object:
`d=0.5gt^2`
where

`d` is the distance

`g` is the gravity of the Earth
`32.17ft/s^2`

`t` is the time in seconds

We know from our problem that Pete slid a domino off a bridge and it took 2.3 seconds to hit the Gully below, so
`t=2.3`. Lets replace that value in our formula to find
`d`:

`d=0.5gt^2`

`d=0.5(32.17)(2.3)^2`

`d=85.1` feet

How can conclude that the domino fell a distance of 85.1 feet.
