In the vacuum, the speed of light is always 3E8 m/s. In fact light is always that speed to you in your local frame. Give an example of where light might be viewed to move “slow” by you, and explain why that happens.

Assume that the speed of light in a vacuum has the hypothetical value of 18.0 m/s. A car is moving at a constant speed of 14.0 m/s along a straight road. A home owner sitting on his porch sees the car pass between two telephone poles in 8.79 s. How much time does the driver of the car measure for his trip between the poles?

Which of these statements are true? The speed of light is approximately 299,792,458 m/s and is uncertain to about 1 m/s The speed of light is the same seen by any observer anywhere in the universe If you are driving along at 100 km/hr, the light leaving your headlights is moving away from your car at 100 km/hr (0.0277 km/s) plus the speed of light, The speed of light is exactly 299,792,458 m/s
Two rockets A & B fly past an observer. "A" moves at constant speed 1000 m/s relative to ground, "B" moves at constant speed 1000 m/s relative to ground and opposite of rocket A. Rocket A sends light opposite to where it is heading.
You are standing on the ground observing the sky. Two spaceships A and B fly past you. Spaceship A is moving at a constant speed of 1000 m/s relative to the ground. Spaceship B is moving opposite to A at speed of 1000 m/s relative to the ground. Spaceship A fires a strobe light that sends out a pulse of light opposite to where it is heading. a) What is the velocity of spaceship A relative to spaceship B? b) What is...

The speed of light in some other universe is 30 m/s. You want to cover a distance of 100 m in 10 s (as measured on your watch) at a constant speed. a. How fast should you run? b. How long did it take you to cover that distance according to an observer at rest with respect to the track? (Carry four sig figs throughout the calculation).
