The mean lifetime of stationary muons is measured

Reference no: EM13662232

The mean lifetime of stationary muons is measured to be 2.3500 µs. The mean lifetime of high-speed muons in a burst of cosmic rays observed from Earth is measured to be 13.500 µs. To five important figures, what is the speed parameter β of these cosmic-ray muons relative to Earth?
