Academics

Solve the given questions:

Question I: An electron is moving east in a uniform electric field of 1.50N/C directed to the west. At point A, the velocity of the electron is 4.47×10⁵m/s pointed toward the east.

Part A: What is the speed of the electron when it reaches point B, which is a distance of 0.375m east of point A?

Question II: A proton is moving in the uniform electric field of part A. At point A, the velocity of the proton is 1.87×10⁴m/s, again pointed towards the east.

Part A: What is the speed of the proton at point B?

Please show all work and steps I am really trying to learn this for my exam.
