Help solving please

In a cathode ray tube, electrons are accelerated from rest by a constant electric force of magnitude 6.40 x 10- N during the first 8.60 cm of the tube's length; then they move at essentially constant velocity another 45.0 cm before hitting the screen. Find the speed of the electrons when they hit the screen. m/s
