Again consider the scenario from the previous problem: A sprinter named Ben has challenged a beam of light to a race in the 100-meter dash. The race is held in a stadium full of spectators
At the start signal, a laser beam is turned on at the start line, pointed down the track. At the same instant, Ben bursts out of the starting blocks at 99% of the speed of light (0.99c). According to Ben, what happens? A) The light beam gradually pulls ahead of him and wins the race because it is going 1% of the speed of light faster than him.
B) The light beam instantly finishes the race, before Ben even has a chance to start.
C) The light beam moves out ahead of him at the full speed of light, winning the race easily.
D) Ben wins the race and becomes a hero.
