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?
