Explanation:
The magnitude of the electric force on this charged particle A depends upon the following
5. the distance between the point charge Q and the charged particle A
8. the amount of the charge on the point charge Q
9. the magnitude of charge on the charged particle A
Remember what acceleration is? It's how fast the speed is changing over a period of time.

So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
Now that you know dv and dt, you can calculate the acceleration a!
