An observer moving toward Earth with a speed of 0.96c notices that it takes 4.8 min for a person to fill her car with gas. Suppose, instead, that the observer had been moving away from Earth with a speed of 0.80c.

How much time would the observer have measured for the car to be filled in this case?

A muon is a type of unstable subatomic particle. When high-speed particles from outer space (sometimes called "cosmic rays") collide with atoms in the upper atmosphere, they can create muons which travel toward the Earth. Suppose a muon created in the atmosphere travels at a speed of 0.941c toward the Earth's surface for a distance of 3.48 km, as measured by a stationary observer on Earth, before decaying into other particles. (a) As measured by the stationary observer on Earth,...

Sam is on a spaceship that travels from Earth to Proxima Centauri at 70% the speed of light, or 0.7c, relative to Earth. Erma is an observer on Earth. From Sam's perspective, 1.35 x 108 seconds passed between when the Earth was near him and when Proxima Centauri is near him First we consider velocity and time: How fast in m/s is Sam moving as measured in the rest frame of the rocket? How fast in m/s is Erma moving...
