Asked by Joe Mama

how fast would you have to be traveling at in a spaceship in order to appear to age 20% slower than your classmate left behind on earth
Answered by drwls
sqrt[1 -(v/c)^2] = 0.8
1 - (v/c)^2 = 0.64
(v/c)^2 = 0.36
v = 0.6 c

60% of the speed of light would be required.

Sorry can you explain how you get 0.64? Square rooting both sides? sqrt of 0.8 is 0.89 on the calculator. Please help.
