Question

A student observes 13.22 min to elapse on her clock. How much time, in minutes, does she observe to elapse during this interval on a clock in the window of her friend's spacecraft, moving by the student with a relative speed of 0.19c

Answer 1

For this question, we will need to use the time dilation formula

`t=\frac{t_0}{\sqrt{1-(v^2)/(c^2)}}`

Where t is the student's time frame

t0 is the time on the friend's spacecraft

and v is the speed (.19c)

13.22 = t0/sqrt(1-v^2/c^2)

t0 = 12.979 minutes
