Question
Part B & C please
In an attempt to reduce the extraordinarily long
travel times for voyaging to distant stars, some
people have suggested traveling at close to the
speed of light. Suppose you wish to visit the red
giant star Betelgeuse, which is 430 ly away, and
that you want your 20,000 kg rocket to move so
fast that you age only 36 years during the round
trip.
Part B
How much energy is needed to accelerate the rocket to this speed?
Express your answer with the appropriate units.
