(2) Pions ("-ons) are subatomic particles with a half-life of 2.6 x 10 seconds as measure by a clock at rest with respect to them. This means that after the passage of this amount of this time as measured by a clock traveling with them, half of them will have decayed. A batch of 50,000 pions with β-092 is created during an experiment at CERN. They are directed along a vacuum line to a detector 50 meters away. How many...
