8,
Chapter 2:
Problem not in text: A baby Vulcan is born on Vulcan and a baby Earthling is
born on Earth 5 years later, in the reference frame of those on Vulcan and
Earth, which are 100 light-years apart.
a) A Klingon ship is traveling at 0.7 c from Vulcan toward Earth. Which
baby is born earlier in the Klingon's frame? How much earlier?
B) A Romulan ship is traveling at 0.7 c from Vulcan away from Earth.
Which baby is born earlier in the Romulan's frame? How much
earlier?
