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?
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
