I need to calculate the acceleration of an proton to a metal plate with a charge of 16 Coulombs(negative charge), 1 meter away. Then I need to calculate the velocity at the moment it passes the plate. Starting Velocity is 0 m/s. What is the velocity and what is the acceleration? This is not homework. When I did this, I got an acceleration of 1.376*1018 m/s2. The velocity is then 1.65891531*109 m/s. Also, how long does it take for the proton to get to the plate.
