Question: A charge of -2.8 µC is fixed in place. From a horizontal distance of 0.0625 m, a particle of mass 4.25 x 10-3 kg and charge -1.7 µC is fired with an initial speed of 12.5 m/s directly toward the fixed charge.
Part A: How far does the particle travel before its speed is zero?
I need help to determine how far the particle travel before its speed is zero.
