Chapter S2, Problem 45EAP
Relative Motion Practice II. In all the following, assume that you and your friends are in free-float reference frames.
- Carol is going away from you at 75 km/hr, and Sam is going away from you in the opposite direction at 90 km/hr. According to Carol, how fast is Sam going?
- Consider again the situation in part a. Suppose you throw a baseball in Sam’s direction at a speed of 120 km/hr. What does Sam see the ball doing? What does Carol see the ball doing?
- Cameron is traveling toward you at 99.9999% of the
speed of light when he turns on a flashlight and points it in your direction. How fast will the beam of light be going when it reaches you?

The Stanford Linear Accelerator (SLAC) accelerates
electrons to c=0.99999997c in a 3.10 km-long
tube.
Part A
If they travel the length of the tube at full speed (they don't, because they are accelerating), how long is the tube in the electrons'
reference frame?
