In a vacuum, a proton (charge = +e, mass = 1.67 x 10-27 kg) is moving parallel to a uniform electric field that is directed along the +x axis (see figure below). The proton starts with a velocity of +8.80 × 10ª m/s and accelerates in the same direction as the electric field, which has a value of +8.60 x 10³ N/C. Find the velocity of the proton when its displacement is +2.0 mm from the starting point.
