Question

1) Consider two inertial reference frames, S and S’ where S’ is moving to the right with a constant velocity of 0.895 c as measured by an observer in S. A stick of proper length 0.878 m moves to the left toward the origins of both S and S’, and the length of the stick is 31.1 cm as measured by an observer in S’. Determine the velocity of the stick as measured by an observer in S’. Answer in units of c.

2)Determine the velocity of the stick as measured by an observer in S. Answer in units of c.

3)What is the length of the stick as measured by an observer in S? Answer in units of m.
