SCutnell, Physics, 10e COLLEGE PHYS gnment Chapter 28, Problem 12 GO A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a planets do not move reiative to each other during the trip. The distance between Mars and Venus is 1.20 x 101l m, as measured by a person on earth d v 0.86c relative to it. Assume that the three (a) What does the Martian measure for the distance between Mars and Venus? (b) What is the time of the trip (in seconds) as measured by the Martian? Go TUTORIAL By accessing this Question Assistance 0 o searcExplanation / Answer
space ship speed, v=0.86c
distance, L=1.2*10^11 m
a)
distance measured by martin,
L'=L*sqrt(1-(v/c)^2)
L'=1.2*10^11*sqrt(1-(0.86c/c)^2)
L'=1.2*10^11*sqrt(1-0.86^2)
L'=0.612*10^11 m
b)
time, t=L'/v
=0.612*10^11/(0.86*3*10^8)
=237.21 sec
