**1. Homework Statement**

A jumper runs horizontally off a 910 meter mountain with speed 4.0 m/s and enjoys a free fall until she is 150 meters above the valley floor, at which time she opens her parachute. Ignore air resistance

## Homework Equations

A) how long is the jumper in free fall.

B) how far from the cliff is the jumper when she opens her parachute?

## The Attempt at a Solution

My attempt is attached with kinematic equations. I want to use Y to find time.

I'm confused on Y. Is it the height 910 meters or 910 meters - 150 meters = 760 meters. Can you explain the vertical component to me?
