Solve the following questions:
Question A: An electron is moving east in a uniform electric field of 1.25 N/C directed to the west. At point A, the velocity of the electron is 4.05 105 m/s toward the east.
Part I: What is the speed of the electron when it reaches point B, 0.365 m east of point A?
Question B: A proton is moving in the uniform electric field of part (a). At point A, the velocity of the proton is1.90 104 m/s, east, what is the speed of the proton at point B?
