Suppose a particle called a kaon is created by cosmic radiation striking the atmosphere. Randomized variables c = 0.89 c t = 1.25 times 10^-8 s It moves by you at 0.89c, and it lives 1.25 times 10^-8 s when at rest relative to an observer. How long does it live, in seconds, as you observe it? Delta t =
Particles called π-mesons are created by accelerator beams. If these particles travel at 2.74 x 108 m/s and live 2.60 x 10-8 s when at rest relative to an observer, how long (in s) do they live as viewed in the laboratory?
A particle starts from rest at x = -1.8 m and moves
along the x-axis with the velocity history shown. Plot the
corresponding acceleration and the displacement histories for the
2.0 seconds. Find the time t when the particle crosses the
origin. After you have the plots, answer the questions.

Two clocks, labelled 1 and 2, are at rest in an inertial frame , S. They are synchronized and separated by a distance, d, as measured in S. A third clock, 3, at rest in S', moves from clock 1 to clock 2 at constant speed, v. An observer in S' measures the distance between clocks 1 and 2 to be 0.72 d. 10 seconds elapses on clocks 1 and 2 in the time taken for clock 3 to travel...
