1. Relativistic Factor. Calculate the value ofthe relativistic factor g for an object traveling at v =0.999c.
2. E = mc2. If precisely 1.00kilogram of mass could be converted completely into energy, for howlong could this amount of energy keep a 100-Watt light bulbshining? (Assume the bulb can operate for a very long time.)
3. Velocity Addition. A relativistic crafttraveling at 0.6c w/r/t to the Earth launches a probe, whichtravels at a velocity of 0.8c w/r/t the craft. What is the velocityof the probe w/r/t the Earth? (It’s not 1.4c.)
