An electron is moving east in a uniform electric field of 1.46 N/C directed to the west. At point A, the velocity of the electron is 4.55x105 m/s pointed toward the east. What is the speed of the electron when it reaches point B, which is a distance of 0.350 m east of point A? Express your answer in meters per second. AEd + 0 E ?
