You have a machine that produces a beam of π(pi) mesons moving at a speed of 0.9938c. In your lab, you aim this beam at a target that is 278.70 m away from your machine. The half‑life for π(pi) meson decays is 26.0 ns.   1. Calculate the time it takes in ns, in the lab frame, for particles to travel from your machine to the target.   2. Find the classically expected fraction of particles that would reach the target without having decayed.   3. Find the time it takes, in the rest frame of the particles, for a particle to travel from the machine to the target.

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
