A woman is 2.0 m tall and has a mass of 60 kg. She moves past an observer with the direction of the motion parallel to her height. The observer measures her relativistic momentum to have a magnitude of 2.30x1010 kg·m/s. What does the observer measure for her height?
L=Lo √1 - (v2/c2)
p=mv/√1 - (v2/c2)
The Attempt at a Solution
I'm pretty sure that these are what the variables are
Lo= 2.0m proper length
we want to solve for L
my problem is I don't know what v is, if I did i could find it.
I saw that L/Lo = mv/p
so L= Lomv/p right?
but i have no idea how to get v. i haven't had math in a while! any ideas or can you help me? I've tried an online equation solver for didn't work...
