Relativity. One concept of relativity theory is that an object moving past an observer at a speed near the speed of light appears to have a larger mass because of its motion. If the mass of the object is when the object is at rest relative to the observer, its mass will be given by the formula m m011 v v2c2 21/2m when it is moving with speed (in miles per second) past the observer. The variable is the speed of light, 186,000 mi/sec. If a proton with a rest mass of 1 unit is accelerated by a nuclear accelerator to a speed of 160,000 mi/sec, what mass will the technicians observe it to have? Round to the nearest hundredth.
