Question
A plank, fixed to a sled at rest in a stationary frame S, is of length Lo and makes an angle of 44°
with the x-axis. Later, the sled zooms through frame S at a constant velocity v parallel to the x-axis and
the angle appears to be 60° relative to the x-axis in frame S. What is the speed of the sled in terms of c,
the speed of light in vacuum?
44°
60
