... Everything’s Relative A muon formed high in the Earth’s atmosphere travels at a speed of 0.990 c for a distance of 4.60 km (as we see it from Earth) before it decays. Observers on Earth believe it takes the muon 1.55x10-5 seconds to reach Earth’s surface. How long does it take in the frame of the m ...

... There are several ways to compute the work for part (b). We can use the definition of work, W = F d cos φ where φ is the angle between the force and the direction the object is moved. Here the force and box’s motion are in the same direction (x̂) so φ = 0◦ and W = F d. The distance the object must b ...
