Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

A constant electric field with magnitude 1.50 x 103 N/C is pointing in the positive x-direction. An electron is fired from x = -0.0200 m in the same direction as the electric field. The electron's speed has fallen by
half when it reaches x = 0.150 m, a change in potential energy of 4.08 x 10-17 J. The electron continues to x = -0.210 m within the constant electric field. If there's a change in potential energy of -8.64 x 10-17
J as it goes from x = 0.150 m to x = -0.210 m, find the electron's speed (in m/s) at x = -0.210 m.
Hint
m/s
