A particle known as a pion lives for a short time before breaking apart into other particles. Suppose a pion is moving at a speed of 0.990c, and an observer who is stationary in a laboratory measures the pion's lifetime to be 2.8 x 10-8 s. (a) What is the lifetime according to a hypothetical person who is riding along with the pion? (b) According to this hypothetical person, how far does the laboratory move Before the pion breaks apart? (a) Number (b) Number i Units Units

Particle A has a rest energy of 1192 MeV and is moving through the laboratory in the positive x direction with a speed of 0.450c. It decays into particle B (rest energy = 1116 MeV) and a photon; particle A disappears in the decay process. Particle B moves at a speed of 0.400c at an angle of 3.03° with the positive x axis. The photon moves in a direction at an angle with the positive x axis. A 0.45c What are the 0.40c photon Ө 3.03⁰ B in MeVs and your answer in three significant digits. in degrees of the photon? Give

A rocket with a proper length of 1500 m moves at a speed of 0.87c directly away from an observer on earth. an astronaut standing at the centre of the rocket fires two electrons at a speed 0.99c through a vacuum pipe. One electron is aimed toward the centre of the rocket, the other toward the rear. a. In the astronaut's frame, calculate the time interval between the electron reaching the front of the rocket and the other electron reaching the rear. b. In the Earth observer's frame, calculate the length of the rocket, and the speed of the two electrons moving towards the front and the rear of the rocket.

A spaceship whose rest length is 283 m has a speed of 0.87c with respect to a certain reference frame. A micrometeorite, also with a speed of 0.87c in this frame, passes the spaceship on an antiparallel track. How long does it take this object to pass the spaceship as measured on the ship? Number Units
