An armada of spaceships that is 1.80 ly long (in its rest frame) moves with speed 0.750c relative to the ground station in frame S. A messenger travels from the rear of the armada to the front with a speed of 0.960c relative to S. How long does the trip take as measured (a) in the messenger's rest frame, (b) in the armada's rest frame, and (c) by an observer in frame S?

*I mostly need an answer to part C please, I have somewhat of an idea for a and b*

A particle of rest energy 800 MeV decays in its rest frame into two identical particles of rest energy 250 MeV. What are the kinetic energies (in MeV), momenta (in MeV/c), and velocities (in units of c) of the daughter particles? Refer to the previous problem. The parent particle moves in the lab with kinetic energy 800 MeV, and one daughter particle is emitted along the parent’s direction of motion. Find the lab kinetic energy (in MeV) for the daughter...

A long, straight wire carrying a current of 3.00 A moves with a constant speed v to the right. A 5-turn circular coil of diameter 1.25 cm, and resistance of 3.25 µΩ, lies stationary in the same plane as the straight wire. At some initial time, the wire is at a distance d = 19.5 cm from the center of the coil. 4.55 s later, the wire is at a distance 2d from the center of the coil. What is...

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.
