Homework Statement
A charge of -3.00 C is fixed in place. From a horizontal
distance of 0.0450 m, a particle of mass 7.20x10^-3 kg and charge
-8.00 C is fired with an initial speed of 65.0 m/s directly toward the
fixed charge. How far does the particle travel before its speed is zero?
Homework Equations
My question is where do I go from KE or really how would I start this problem off?
The Attempt at a Solution
I thought that it should start off with KE so I put 1/2mv^2
