Find an approximate expression for the proton's kinetic energy. (Use the following as necessary: ?, mp for the mass of proton, and c for the speed of light. In this case, (? - 1) ˜ ?.)
KE = ________

(b) Find the speed of the proton. (The rest energy of a proton is 938.3 MeV. Enter your answer to five decimal places.)

______ c

Explanation / Answer

0.5mv^2=938.3x10^6 v^2=938.3x10^6/(1.66x10^-27*0.5) v=1.06x10^18 m/s
