An electron is accelerated from rest through a potential

Question

Solve the all parts of given question:

Question: An electron is accelerated from rest through a potential difference that has a magnitude of 2.60 x 10⁷ V. The mass of the electron is 9.11 x 10^-31 kg, and the negative charge of the electron has a magnitude of 1.60 x 10^-19 C.

Part I: What is the relativistic kinetic energy (in joules) of the electron?

Part II: What is the speed of the electron? Express your answer as a multiple of c, the speed of light in a vacuum.

Please show all work so I can fully understand all concepts! Thank you.
