50PRACTICE PROBLEM
Pions, which are produced when cosmic rays collide with particles in Earth's atmosphere, are created 40 km above Earth and must reach a detector 1.0 km underground (total distance: 41 km). A pion's mean lifetime at rest is 3.00 μs, and its mass is 150 MeV/c². Determine the minimum speed and kinetic energy needed for the pion to reach the detector, accounting for relativistic time dilation.
