SUMMARY
The discussion centers on calculating the apparent mass of a lead brick with a rest mass of 27 kg when observed at relativistic speeds. Specifically, the apparent mass is to be determined for two scenarios: the brick moving away at 0.73c and the observer moving toward it at -0.73c. The relevant concept is "relativistic mass," which requires the application of the appropriate equations from the theory of relativity. The user expresses frustration due to a lack of instruction on these equations and reliance on a non-functional online calculator.
