Question
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 +9.90 × 104 m/s and accelerates in the same direction as the electric field, which
has a value of +1.50 × 10³ N/C. Find the velocity of the proton when its displacement is +2.0
mm from the starting point.
