    An electron is a subatomic particle (m = 9.11 x 10^-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.32 x 10^5 m/s to a final velocity of 2.56 x 10^6 m/s while traveling a distance of 0.0934 m. The electron's acceleration is due to two electric forces parallel to the x axis: F1 = 7.82 x 10^-17 N, and F2, which points in the -x direction. Find...
