You shoot a bullet with a speed of 0.6c to your right.
Then, you get on a magical car and begin to travel to your left
with a speed of 0.8c. (c is the speed of light)
a. What is the velocity of your magical car relative to the bullet?
Explain.
b. Looking back at the direction where you previously shoot the
bullet, can you observe the bullet now? Explain.
Homework Answers
sign convention:
Right : Positive
Left : Negative
speed of the bullet, VB = 0.6c
speed of the magical car, VC = -0.8c
a) sol.
velocity of car relative to the bullet,VCB = VC - VB
VCB = -0.8c - 0.6c
VCB = -1.4c
speed of the car w.r.t bullet is 1.4c towards left.
b) sol.
Now from inside the car, when we observe the bullet:
the speed of the bullet that we will observe that, VBC = VB - VC
VBC = 0.6c - (-0.8c)
VBC = 1.4c (towards right)

9.1 Lorentz Contraction Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can...

You are kidnapped by armed political-science majors (who are upset because you told them that political science is not a real science). Although blindfolded, you can tell the speed of their car (by the whine of the engine), the time of travel (by mentally counting off seconds), and the direction of travel (by turns along the rectangular street system). From these clues, you know that you are taken along the following course: 52 km/h for 2.0 min, turn 90° to...

Example 29-9 depicts the following scenario. At starbase Faraway Point, you observe two spacecraft approaching from the same direction. The Picard approaches starbase Faraway Point with a speed of 0.813 c, and the La Forge approaches the starbase with a speed of 0.900 c. Suppose the Picard now launches a probe toward the starbase. D) Faraway Point starbase launches a probe toward the approaching starships. The probe has a velocity relative to the Picard of -0.900 c. The Picard approaches...
