Question

Mars rotates about its axis once every 88 642 s. A spacecraftcomes into the solar system and heads directly toward Mars at aspeed of 0.800c. What is the rotational period of Marsaccording to the beings on the spaceship?

a. 181 000 s
b. 88 600 s
c. 105 000 s
d. 53 100 s
e. 148 000 s Mars rotates about its axis once every 88 642 s. A spacecraftcomes into the solar system and heads directly toward Mars at aspeed of 0.800c. What is the rotational period of Marsaccording to the beings on the spaceship? 181 000 s 88 600 s 105 000 s 53 100 s 148 000 s

Explanation / Answer

We know that :                        t`   = t / (1 - v2 /c2 ) Given :               t   = 88642 s                v    =   0.800c                             t`   =  88642 / [1 - ((0.80c)2 / c2 )]                       = 147736.667   s                       ˜  148000   s Hope this helps u!
