Tutorial Exercise The average lifetime of a pi meson in its own frame of reference (i.e., the proper lifetime) is 2.6 x 108 s. (a) If the meson moves with a s on Earth? of 0.85c, what is its mean lifetime as measured by an observer (b) What is the average distance it travels before decaying, as measured by an observer on Earth? (c) What distance would it travel if time dilation...

A pion is an unstable particle that has a mean lifetime of 2.55 x 10^-8 s. Thi si the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the pion. An average pion is traveling at 0.230 c relative to Earth. How far does it travel in its lifetime, relative to Earth?

30. A mass of 0.40 kg is dropped from rest in a medium of- fering a resistance of 0.2 , where u is measured in meters per second. (a) If the mass is dropped from a height of 25 m, find its velocity when it hits the ground. (b) If the mass is to attain a velocity of no more than 8 m/s, find the maximum height from which it can be dropped. (c) Suppose that the resistive force is...
