A Rigellian spaceship fleeing from battle passes Space Station Delta at an essentially constant velocity of 3/5 in the +x direction: let this be the origin event O. At event B, 80 seconds after even O as measured in the its own frame, Space Station Delta fires a photon torpedo (which travels at the speed of light) toward the fleeing ship. At event C, 100 seconds after event O in the space station frame, the Rigellians fire a laser flash (which also travels at the speed of light) back toward Space Station Delta. This laser flash destroys the torpedo at event D. a. On a sheet of hyperbola graph paper, draw the worldlines of Space Station Delta and the Rigellian ship. b. Locate events O, B, and C on the diagram. c. Draw and label the torpedo and laser flash worldlines and locate event D. What are its coordinates?

Recall, from this chapter, that the factor gamma (γ) governs both time dilation and length contraction, where When you multiply the time in a moving frame by γ, you get the longer (dilated) time in your fixed fame. When you divide the length in a moving frame by γ, you get the shorter (contracted) length in your fixed frame. Assume that rocket taxis of the future move about the solar system at half the speed of light. For a 1-hour trip as measured by a clock in the taxi, a driver is paid 10 stellars. The taxi-driver’s union demands that pay be based on Earth time instead of taxi time. If their demand is met, show that the new payment for the same trip would be 11.5 stellars.

To understand length contraction and time dilation. An inertial frame of reference is one in which Newton's laws hold. Any frame of reference that moves at a constant speed relative to an inertial frame of reference is also an inertial frame. The proper length l0 of an object is defined to be the length of the object as measured in the object's rest frame. If the length of the object is measured in any other inertial frame, moving with speed u relative to the object's rest frame (in a direction parallel to l0), the resulting length lll is given by the length contraction equation l= l0 *sqrt(1-u^2/ c^2) where c is the speed of light. Similarly, if two events occur at the same spatial point in a particular reference frame, and an observer at rest in this frame measures the time interval between these two events, the time interval so measured is defined to be the proper time Δt0. When the time interval is measured in any other inertial frame, again moving with speed uuu relative to the…

An interstellar space probe is launched from Earth. After a brief period of acceleration, it moves with a constant velocity, 74.0% of the speed of light. Its nuclear-powered batteries supply the energy to keep its data transmitter active continuously. The batteries have a lifetime of 19.4 years as measured in a rest frame. Note that radio waves travel at the speed of light and fill the space between the probe and Earth at the time the battery fails. (a) How long do the batteries on the space probe last as measured by mission control on Earth? (Ignore the delay between the time the battery fails and the time mission control stops receiving the signal.) yr (b) How far is the probe from Earth when its batteries fail as measured by mission control? (Ignore the delay between the time the battery fails and the time mission control stops receiving the signal.) ly (c) How far is the probe from Earth as measured by its built-in trip odometer when its batteries fail? ly (d) For what total time…

Please derive the Lorentz transformation equations for velocities. For an object, the velocity components seen in reference frame S are: ??, ??, ??. There is a reference frame S’ is moving relative to reference frame S in the direction of +?̂. Derive ?′?, ?′?, ?′?. Please show your derivation details.

An astronaut is traveling at a constant velocity of 0.8 times the speed of light (c = 3 x 10^8 m/s) away from a space station. If the astronaut's clock is ticking normally, but the space station observes their clock to be running slower due to time dilation, calculate the time interval experienced by the astronaut during a 1-hour period according to their own clock.

1. You are an observer in a 100-m long spacecraft traveling from the earth to the moon at 0.8c. (a)What is the proper length of the spacecraft? (b) For a proper time interval of 1 sec., the relativistic time interval for the spacecraft measured from the earth reference frame would be: (c)Time dilation does not apply to all time-dependent physical and biological processes. T/F? (c) What is the relativistic length, DL measured from the reference frame of earth? (d) An APOLLO crew left a flat mirror reflector on the surface of the moon (for all you deniers out there, in the 50th anniversary year of APOLLO 11!). If the average surface-to-surface distance from the earth to the moon is 3.83 x 10^8 m, then how long does it take moonlight to reach earth?

In frame S, event B occurs 2 ms after event A and at Dx = 1.5 km from event A. (a) How fast must an observer be moving along the +x axis so that events A and B occur simultaneously? (b) Is it possible for event B to precede event A for some observer?(c) Draw a spacetime diagram that illustrates your answers to (a) and (b). (d) Compute the spacetime interval and proper distance between the events.

The proper length of one spaceship is three times that of another. The two spaceships are traveling in the same direction and, while both are passing overhead, an Earth observer measures the two spaceships to have the same length. If the slower spaceship has a speed of 0.354c with respect to Earth, determine the speed of the faster spaceship. (Give your answer to at least 3 significant figures.) |c
