Question

Special relativity problems

a)

A windowless spaceship falls freely to the ground along a vertical path. The physicist observes two stationary objects inside the spacecraft, which are at a distance of 1 m from each other when the astronaut is at 100 km altitude. How accurate distance measurement does the physicist need to do to discover that he is not in complete inertia? (Do not take into account the Earth's atmosphere)

b)

Assume that the criterion S moves at a rate v seen from another criterion S. Furthermore, suppose that the initial points of the criteria coincide with time t = 0. Find the Galilei transformation that links the spatial coordinates of the reference systems.

Answer 1
