An unstable particle produced in an accelerator experiment travels at constant velocity, covering 1.00 m in 3.40 ns in the lab frame before changing (“decaying”) into other particles. In the rest frame of the particle, determine

  1. how long it lived before decaying,
  2. how far it moved before decaying.
