A cosmic ray proton passes along the left-right width of a page with a relative speed v and total energy 14.20 nJ. According to your measurements, that left-right width is 21.0 cm. (a) What is the width according to the proton's reference frame? How much time did the passage take according to (b) your frame and (c) the proton's frame? (a) Number 0.0022 Units m v (b) Number i 0-700 Units How much work must be done to increase the speed of an electron from (a) 0.25c to 0.27c and (b) from 0.93c to 0.95c? Note that the speed increase is 0.02c in both cases. (a) Number 4.3E-16 Units (b) Number 1.54e-15 Units
