Textbook Question
Chapter 37, Problem 37.43P
After being produced in a collision between elementary particles, a positive pion (π+) must travel down a 1.90-km-long tube to reach an experimental area. A π+ particle has an average lifetime (measured in its rest frame) of 2.60 × 10−8 s; the π+ we are considering has this lifetime, (a) How fast must the π+ travel if it is not to decay before it reaches the end of the tube? (Since u will be very close to c, write u = (1 − Δ)c and give your answer in terms of Δ rather than u.) (b) The π+ has a rest energy of 139.6 MeV. What is the total energy of the π+ at the speed calculated in part (a)?

- An outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in the figure, but that the ball's speed after the bounce is one-half of what it was before the bounce. 8 (a) Assuming the ball is always thrown with the same initial speed, at what angle & should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 35.0° with no bounce (green path)? 24 (b) Determine the ratio of the time interval for the one-bounce throw to the flight time for the no-bounce throw.
