A) An observer in a lab attached to the earth sees a uranium atomfission and observes that one of the neutrons takes about 30 min.to decay. What is the observer's best estimate of the speed andenergy of that neutron before it decays?
B) An observer in a rocket ship passes over the lab at a speed of0.8c relative to the Earth, and sees the neutron appear as a resultof fission and then decay. The observer's motion is parallel to thedirection in which the neutron is moving. How long doe it take theneutron to decay according to the observer in the rocket? What ishis estimate of the neutron's speed and energy?
