Suppose a muon produced as a result of a cosmic ray colliding with a nucleus in the upper atmosphere has a velocity v = 0.9500c. Suppose it travels at constant velocity and lives 1.52 µs as measured by an observer who moves with it (this is the time on the muon's internal clock). It can be shown that it lives for 4.87 µs as measured by an earth-bound observer (see Example 26.1 in the textbook). Give all answers correct to 4 significant figures.
(a) How long would the muon have lived as observed on earth if its velocity was 0.0700c?
(b) How far would it have traveled as observed on earth?
(c) What distance is this in the muon's frame?
When the pitcher throws his fastball aimed at the clay, the ball becomes embedded in the clay and the two swing up to a maximum height of 0.11 m. If the mass of the baseball is 0.21 kg, find out the speed of the pitch. Please provide step by step ..
A bead with a mass of 0.050g and a charge of 20nC is free to slide on a vertical rod. At the base of the rod is a fixed 10nC charge. In equilibrium, at what height above the fixed charge does the bead rest?
