In this problem we will observe how the momentum of an electron changes as its velocity approaches the speed of light. The mass of an electron is 9.109 × 10-31 kg Part (a)  First, what is the momentum of an electron which is moving at the speed of a car on a highway, say 31 m/s, in kilogram meters per second?   Part (b)  What is the momentum of an electron moving at 18 % of the speed of light, in kilogram meters per second?    Part (c)  What is the momentum of an electron moving at 81 % of the speed
