Question
1. A spaceship travels with a speed of 0.9 c as it passes by the Earth on its way to a distant star, as shown in the diagram below. The pilot of the spaceship measures the length of the moving ship as 30 m.
Determine its length as measured by a person on Earth. Answer in units of m.
2.The pilot of the spaceship observes that the spaceship travels for 7 years. Determine how much time has passed according to a person on Earth. Answer in units of years.
I NEED ANSWERS TO BOTH QUESTION. PLEASE AND THANK!
0.9 c- EarthExplanation / Answer
Let L0 =30 m
v=0.7c
L= L0 Sqrt(1-(v^2/c^2))
L = 30* Sqrt(1-(0.9)^2)
L= 13.07 m
2) T =T0 / Sqrt(1-(v^2/c^2))
T=7 / Sqrt(1-(0.9)^2)
T = 16.05 Years
