# Velocity and Distance

I've encountered this one physics problem that I can't quit figure out:

"While skiing, Ellen encounters an unexpected icy bump, which she leaves horizontally at 12.0 m/s. How far out, horizontally, from her starting point will Ellen land if she drops a distance of 7.00 m in the fall?"

You need to find how long it will take to fall 7m. Use that time and the given horizontal velocity to find how far forward the skier travels.

What have you done so far on the problem?

This is how far she falls: $y = - \frac {1}{2} g t^2$

Find out how long it takes her to fall 7m. You should then be able to find out how far she moves horizontally.
