- 1. If a subatomic particle moves close to the speed of light. Its decay would occur ___? 2. A space explorer travels between asteroids that are 100 000 m apart. His/her space probe travels with constant speed of 0.8c=2.4x108 m/s. What is the time of the trip between asteroids measured by observer on one of the asteroids? Write your answer rounded to 2 decimal places in msA ship is heading off to Bernard's star at 0.700c. As it passes a space station (at rest with respect to the Earth) a few days out from Earth, the ship fires a "photon torpedo" in the forward direction and another in the reverse direction. the torpedoes have a speed relative to the ship of 0.700c. On a space-time diagram, determine the direction and speed of each torpedo as seen by the station. Check your answers using the relativistic addition of velocities formula.Susan is running to the right, in the +x-direction, at 2 m/s. A bird flies past her, traveling to the left at 10 m/s. What is the bird's velocity in Susan's reference frame? Susan is running to the right, in the +x-direction, at 2 m/s. A bird flies past her, traveling to the left at 10 m/s. What is the bird's velocity in Susan's reference frame? 12 m/s 10 m/s 8 m/s -8 m/s -10 m/s -12 m/s
- A star is 12.2 ly (light-years) from Earth. HINT (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.36 ly? m/s (b) What is the journey's travel time in years as measured by a person on Earth? NO SCIENTIFIC NOTATION ANSWERS THANK YOUWhich of the following are part of the first postulate of Einstein's Special Theory of Relativity? Time and weight are relative to the motion of the observer. All the laws of physics are the same in all inertial frames of reference. Absolute motion can always be detected. a I only b II only c III only d I, II, and IIIA newly constructed spaceship has a length of 100.0 m (as measured in the rest frame).

- Your answer is partially correct. Twins who are 19.0 years of age leave the earth and travel to a distant planet 12.0 light years away. Assume that the planet and earth are at rest with respect to each other. The twins depart at the same time on different spaceships. One twin travels at a speed of 0.894, and the other twin travels at 0.412c (a) According to the theory of special relativity, what is the difference between their ages when they meet again at the earliest possible time? A₂-A₁- (b) Which twin is older? The second twin is older RAA rocket is traveling through space and its Lorentz factor (y) is 3.9. Determine the rocket's speed (in terms of c) and the ratio of its kinetic energy to its total energy. V= ? X c KE/E= ?The length of a rod seems shortest to an observer when it moves in a specific direction. What change would he observe when the direction of rod changes by 900? O A.
