## Homework Statement

Thelma and Louise's car falls off the edge of the Grand Canyon and plunges to certain catastrophe below. The depth of the canyon at this point is 500 m. (Assume it drops off)

A) How long will it take the vehicle to impact the canyone bottom?

B) What will the vertical impact velocity be? Do you think they will survive, even with air bags?

## Homework Equations

d = vit + 1/2at^2

d = (vi+vf)t

2

## The Attempt at a Solution

d - 500m

ag = -9.81 m/s^2

vi = 0m/s

t =?

Since you cant solve for t, i solved for Vf.

Would the Vf be a negative number?

Then, i pluged the vi and vf into the 2nd equatioon above, but the answer i got was different from the answer given.
