6. What is the final speed of a electron that has an initial speed of 2 x 106 m/s that is accelerated through a potential difference of 150 V?

The difference in electric potential between a thunder cloud and the ground is 2.13  108 V. Electrons move from the ground which is at a lower potential to the cloud which is at a higher potential. Determine the change in electric potential energy of one of the electrons that move to the cloud.
