Rocket taxis of the future move about the solar system at half the speed of light. Drivers receive $100.00 per hour as measured by clocks in the taxis. The taxi drivers’ association demands that the pay be based on earth time instead of the taxi time. If their demand is met, by what fraction will their wages change? Would this be beneficial for them or not?
Supposed a truck, 10 - m long travels at a speed of 2.5 x 108 m/s relative to two observers, Ana and Marie. Both observers have a can of orange spray paint, which they fire simultaneously when the respective ends of the truck are directly in front of them. When the truck stops, Ana,
Marie and the truck driver look at the orange paint spots. How far apart are these spots? How would the truck driver interpret the same event while in the moving truck?
A 1-kilometer long train is travelling at a speed of 100 mi/hr. How long is the train as observed by a passenger who was left standing on the platform? Is length contraction observed? Explain your answer briefly.
