A spacecraft with circular (north and south sides) of diameter 32 meter passes Earth moving eastward (in relation to you)), at the speed of an electron whose energy is eleven times its rest energy.
(a) Find the speed of the spacecraft in units of c, the speed of light in a vacuum.
(b) Find the dimensions of the circular faces according to the earthbound observer?
(c) According to this earthbound observer determine what is the lifetime of copper-64 nucleus on the captain's worktable, in the spacecraft if a copper- 64 nucleus at rest has the lifetime of 12.7 hour?
