An rocket flies to the Moon (a distance of 300,000 km) at a speed of 1500 m/s.

a) How much time does the one-way trip take in the Earth's frame of reference?

b) What ? What is ? (Your calculator may show "1" for , so you will have to use the binomial approximation to find .)

c) Will the time for the trip measured in the rocket's frame be slightly more or slightly less than the time measured in the Earth frame?

d) What is the difference (in seconds) between the two time measurements (Earth's frame vs rocket's frame)?
