Relativity
PLEASE, ANSWER ALL THREE BELOW. LIST THEM IN ORDER. THANKS.
As measured in Earth's rest frame, a spaceship traveling at 0.964c takes 14.9 y to travel between planets. How long does the trip take as measured by someone on the spaceship?
As measured in Earth's rest frame, a spaceship traveling at 0.964 takes 14.9 y to travel between planets. How long does the trip take as measured by someone on the spaceship?
9.68 y
Someone in Earth's rest frame says that a spaceship's trip between two planets took 10.0 y, while an astronaut on the space ship says that the trip took 5.63 y. Find the speed of the spaceship in terms of the speed of light.

Calculate the mass of a proton in MeV/c2.
m = MeV/c2Explanation / Answer
a) time on ship = 14.9/gamma = 14.9*sqrt(1-0.964^2)= 3.96 years
b)
now
5.63 = 10*sqrt(1- beta^2)
beta = 0.826 c
c) mass of proton = 938.27 MeV/c^2
