Imagine Bob lives on the earth at rest. Sara is traveling past the earth with a velocity of 9600 m/s. If a meteor moving in the same direction passes Sara, Bob sees the meteor velocity to be 15400 m/s.

A) What is the magnitude of the velocity of the meteor seen by Sara?

B) Now assume that Sara's speed is 1.25×108 m/s and the meteor speed is 2.13×108 m/s. What is the magnitude of the velocity of the meteor that Sara sees now?

C) Suppose that a photon of light is passing Sara instead of a meteor. Bob measures the photon speed to be c, the speed of light. What speed does Sara measure?
