- 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 29 m/s, in kilogram meters per second?Suppose that a person has an average heart rate of 91.0 beats/min. (Express your answers to problems in this section to the correct number of significant figures and proper units.) How many beats does he or she have in 6.0 y? How many beats does he or she have in 6.00 y? How many beats does he or she have in 6.000 y?Please I need help with the second part of the question, It wasn’t 1.003x10^6 or 1003000 please help
