- An observer measures a spacecraft’s length to be exactly half of its rest length. a) What is the speed of the ship relative to the observer’s frame of reference? b) By what factor do the spaceship’s clocks run slow relative to clocks in the observer’s frame?Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruising speed of 0.790c for a 17.5 year round trip (according to Allison). Neglecting the brief time periods required for the acceleration of the ship during blastoff and turnarounds, find the difference in age between Nora and Allison when they are reunited, difference in age: years Who is older? Allison They are still the same age. need more information Nora4. Bob is moving away from Alice with speed of 0.5c. Carlos is moving away from Alice and to Bob with speed of 0.8c. What is the speed of Carlos as measured by perpendicular Bob?
- 3) In a frame S, two events are observed by Max: event 1: a pion (pi meson) is created at rest at the origin, and event 2: the pion disintegrates (decays) after time T. Susan is an observer in frame S', and is moving in the positive direction along the positive x-axis, with speed v. Susan observes the same two events in her frame. The two frames coincide at time t = t' = 0. a) Find the positions and timings of these two events in Susan's frame according to the Galilean transformation. b) What are the positions and timings of the two events in Susan's frame according to the Lorentz transformation? Provide details of how you calculated your results, and explain the differences be- tween the answers (a) and (b).A spacecraft travels at 1.5 X 108 m/s relative to Earth. A process onboard the ship as measured by a stationary clock on Earth takes 85 min. How long would the same process take as measured by a clock onboard the ship?Two clocks are synced on Earth. A ship takes one of the clocks during it journey and comes back. The clock on the ship is observed to run at a speed of only 2/5 that of a similar clock at rest on Earth. Calculate the velocity of the ship during its journey.
- 6. An unknown ship is traveling at 0.8 c to the left as measured by someone on the Earth. Earth sends space ship traveling to the right at 0.9 c to intercept the ship. Eanh a) What is the velocity of the alien space ship as measured by the ship from Earth? b) If the Earth ship fired a laser at the alien ship, what would be the velocity of the laser according to someone on the alien ship?18 Part 2 of 2 + eBook Hint Print References A spaceship is moving away from Earth with a constant velocity of 0.840c with respect to Earth. The spaceship and an Earth station synchronize their clocks, setting both to zero, at an instant when the ship is near Earth. By prearrangement, when the clock on Earth reaches a reading of 1.00×104 S, the Earth station sends out a light signal to the spaceship. According to an Earth observer, what is the reading of the clock on Earth when the signal is received?View Policies Current Attempt in Progress (Come) back to the future. Suppose that a father is 20.00 y older than his daughter. He wants to travel outward from Earth for 2.000 y and then back to Earth for another 2.000 y (both intervals as he measures them) such that he is then 20.00 y younger than his daughter What constant speed parameter 3 (relative to Earth) is required for the trip?
