The kinetic energy of the electron is

where

is the mass of the electron and v its speed. Since we know the value of the kinetic energy,

, we can find the value of the speed v:
Answer:
yes
Explanation:
Let's solve your equation step-by-step.
4x+3=−5
Step 1: Subtract 3 from both sides.
4x+3−3=−5−3
4x=−8
Step 2: Divide both sides by 4.
4x / 4 = −8 / 4
x=−2

C. Eastward. Acceleration is the change in speed so it can be a positive (speeding up) or negative (slowing down) acceleration
