A1. (a) A large rocket ship traveling away from Earth at a speed of 0.4c launches ashuttle which also travels in the direction away from earth. From an observeron the rocket ship the shuttle is receding at a speed of 0.6c.Calculate the velocity of the shuttle for an observer on Earth.(b) A spaceship leaves Earth and travels in a fixed direction with constant speed0.80c in the Earth's reference frame. A video call is set to be made fromthe spaceship exactly one year after launch, as measured by a clock on thespaceship.(i) Calculate how far away from Earth the spaceship is (in light-years) whenthe video call is made.(ii) Calculate how long after the departure time, as measured on Earth, beforethe video call is received on Earth. The call is transmitted by radio waves.

We will use the relativistic velocity addition formula and time dilation formula to answer the…

A space shuttle passes over the Earth at v = 0.90c speed. If the length of space shuttle observed by the astronaut inside is 100meters, what is the length of it observed by someone on Earth?
Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has speed v = 0.82c. The muon then travels at constant speed and lives 1.5 μs as measured in the muon's frame of reference. (You can imagine this as the muon's internal clock.) 1)how many meters does it travel as observed on the earth? 2)how many meters is this in muon's frame?
