Say no = 1.00x10' muons traveling at 0.999c are measured at 5000 m above sea level. the number of muons surviving after a time tis n= no exp[- ]where #12 = 1.52 10-s is known as the muon half-life. how many would you expect to reach sea level using galilean relativity and how many using einstein's special relativity?

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
