PHY112 – Lab 13 – Worksheet Name __Vincent Guzman __ Sections _____________ Procedures:  Below are seven scenarios or “thought experiments.” Based on the  readings in the textbook and other books or Web sites you may have used, provide ( in  your own words ) explanations for each scenario. 1. Person A is standing in a parking lot. Person B is riding in a car that is moving with  velocity ( v ). Person B shines a flashlight in the direction he or she is moving. What  speed of light will each person measure?
2.  The average life span in the United States is about 70 years. Does this mean that it is impossible for an average person to travel a distance greater than 70 light years away  from the Earth? (A light year is the distance that light travels in a year.) This is not a yes  or no answer. Explain your reasoning.
