(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

To find "E" in an electrostatics problem when you are given the velocities and/or distance, you would use the formula E = Δv/d.

Given the information below to start out with, derive the equation E = Δv/d and explain what happens to the negative signs (where do they go and why) as you continue to derive the equation.

Given information:

ΔEp = -ΔEk

Δv/d = Eki - Ekf

Δv/d = -1/2mvf^2

2. Relevant equations

E = Δv/d

3. The attempt at a solution

For me to derive this equation any further to the equation E = Δv/d I will have to somehow get rid of that negative, I was just wondering, what happens to that negative?
