A stick of length L moves past you, parallel to its length, at speed v. Let your frame be S, and the stick's frame be S'. Call the event when the front of the stick passes you Event A, and the event when the back of the stick passes you Event B. Draw the Minkowski diagram to scale, including both frames, and putting in both events.

A spaceship initially at rest is propelled to a Lorentz factor ? = 8 (speed of 0.9922c). The mass of the spaceship is 20,000 kg; neglect the mass of the fuel. a. How much energy (in J) would be required to do this? [Hint: Use equation (9-5). Your answer will be in joules (J) if you use c =3.0 ?108 m/s, since 1 J = 1 kg m2/s2.] [2 points] b. How much mass in fuel would be needed to...

A spaceship A (at rest in inertial frame A) of proper length L0=50.0m is moving in the +x direction at a speed v=0.750c as measured in the Earth frame. Another spaceship B (at rest in inertial frame B) is moving on a parallel path in the opposite direction ( -x ) with ux=-0.600c as measured in the Earth frame. The two spaceships pass each other. a. What is the velocity and speed parameter of spaceship B in inertial frame A,...

What is the proton's speed as it passes through point P?

A proton follows the path shown in (Figure 1). Its initial speed is v0 = 1.4 x 10^6 m/s. Part A What is the proton's speed as it passes through point P? Express your answer to two significant figures and include the appropriate units.

A spaceship of proper length Lp = 500 m moves past a transmitting station at a speed of 0.83c. (The transmitting station broadcasts signals that travel at the speed of light.) A clock is attached to the nose of the spaceship and a second clock is attached to the transmitting station. The instant that the nose of the spaceship passes the transmitter, the clock attached to the transmitter and the clock attached to the nose of the spaceship are set...

You are in a spaceship making measurements very close to a black hole. A partner's spaceship is orbiting the black hole at a much larger radius. Your partner sends messages to you using visible light pulses from a laser. When you receive the messages, do you expect to detect radio waves or gamma waves? Why? The answer is gamma waves, but I don't understand.
