Answer:
It moves 7.088 times faster that a clock at rest.
Explanation:
Using Einstien's special theory of relativity we have
observer's Time = [tex]\frac{T_{o}}{\sqrt{1-(\frac{v}{c})^{2}}}[/tex]
where To is proper time
Applying values we get
Observer's time =[tex]\frac{T_{o}}{\sqrt{1-(\frac{0.99c}{c})^{2}}}\\\\=7.088T_{0}[/tex]
This for the clock on spaceship it moves 7.088 times faster than that on earth
