Solve the following questions:
Question 1: What is the speed of an electron that has been accelerated to the point at which its total energy is 9.5 times its rest mass? (The rest mass of an electron is 9.11x10-31 kg.)
v =__________ m/s
Question 2: What is the electron's total energy at this velocity?
E=_________J
Question 3: What is the electron's relativistic kinetic energy at this velocity?
K=__________ J
Question 4: Let's assume for a minute that Newtonian mechanics holds at this velocity. What would the electron's Newtonian kinetic energy be at this velocity?
KNewton=_______ J
If possible just a brief explanation how you got the answer?
