**1. Homework Statement**

A person throws a stone vertically downward with an initial speed of 16.0m/s from the roof of a building 58.2m above the ground.

**What velocity does the stone have at impact?**

**2. Homework Equations**

**initial x= 58.2m initial vox=16.0m/s ax= 9.81m/s^2 xfinal=0 vx=?**

**2a(x-xo)=vx^2-vox^2**to find t= 3.88

**vx=vox+axt**plug in a number including t=3.88 vx= 54.1
