Question

HLPaper 1AStandard

A particle decays after traveling $600\,\text{m}$ in Earth's frame while moving at $0.80c$ . What is the particle's lifetime in its own rest frame?

Question

HLPaper 1AStandard

In Earth's inertial frame, two events are simultaneous and are separated by a distance of $1.80\times 10^8\ \text{m}$ . What is the magnitude of the time difference between the events in a frame moving at $0.60c$ in the direction from the first event to the second?
