Direction: Answer in paper, show all solution and explain.

Direction: Solve each of the given problems completely by showing all solutions - data, equation, substitution, computation, and final answer. Problem 1 Calculate the length contraction of a 2000-cm object that travels at a velocity of 0.85c. Problem 2 An object is travelling at a speed of 75% that of light for 10 years. Determine how much time is detected by an observer at rest.Relativistic Factor y = relativistic factor Time Dilation Ato At = time At = = YAto Ato = proper time 1 measured by an observer At = YAto Length Contraction L = Length contraction L = Lo 1 2 Lo = proper length measured by an observer L= Lo V Relativistic Mass mo m = m = relativistic mass mo = rest mass relative to 1 an observer Relativistic Momentum mu P = p =relativistic momentum m = rest mass 1 u = velocity relative to an p = ymu observer Rest Energy Eo = mc2 m = rest mass Relativistic Energy mc2 m = rest mass E = E = ymc2
