Problem 2.1 asks students to calculate the Lorentz factor for an object moving at 0.6c relative to an observer. Using the equation above, we can plug in the values:
This means that the astronaut will experience time passing 1.67 times slower than the observer on Earth. Arthur Beiser Modern Physics Solutions Of Chapter 2 Pdf
Problem 2.10 asks students to calculate the length contraction factor for an object moving at 0.9c relative to an observer. The length contraction factor is given by: Problem 2
