As measured in Earth's rest frame,a spaceship traveling at 0.964 c takes 11.2 y to travel between planets.How long does the trip appear to take for someone on the spaceship?
A)2.98 y
B)7.28 y
C)42.1 y
D)30.7 y

Question

Quizplus · Accepted Answer

The time experienced by someone on the spaceship is shorter due to time dilation, which is calculated using the Lorentz factor. The proper time is 11.2 y * sqrt(1 - 0.964^2) = 2.98 y.
