Homework Statement
A charge of -0.061 C is intiialy moving to the right with a velocity of 54m/s. It is moving in an electric field of 888N/C to the right, and has a mass of 0.72 kg. What is the maximum distance the charge moves to the right? What velocity does it have when it returns to the origin? What velocity does it have at x=5.75m?
Homework Equations
I don't know how to start.
The Attempt at a Solution
I tried using the electric field E=kq/r2but I can't get the solution.
