2. Suppose a space vehicle with a rest mass of 150 000 kg travels past the International Space Station at a constant speed of 2.6 x 10° m/s with respect to the I.S.S. When an observer on the I.S.S. measures the moving vehicle, her measurement of the space vehicle length is 25.0 m. a. Determine the relativistic mass of the space vehicle. b. Determine the length of the space vehicle as measured by an astronaut on the space vehicle. Note: For any required calculation, be sure to include a complete solution process with a summary statement and a final answer with the correct significant figures.

A free neutron has a mean lifetime of about 14.9 minutes when it is viewed from an inertial reference frame at rest with respect to the neutron. The neutron has a mass of 1.675 x 10^-27 kg.a. If the neutron is traveling at 0.9995 c, what is its lifetime as measured by a lab-based (Earth-based) observer?b. What is the neutron's rest energy in MeV (mega electron-volts)? Conversion: 1 MeV=1.602 x10^-13c. What is the neutron's kinetic energy in MeV when it is traveling at 0.9995c?
