An observer on a spacecraft moving .6c relative to the earth finds that a car takes 50 minutes to take a trip. How long does the trip take the driver of the car?(the problem just glosses over the 50mph or so the car would be going)(adsbygoogle = window.adsbygoogle || []).push({});

Ok, so v=.6c, and we're using the lorentz transformation for time, so

To=gamma*T and where I always get mixed up is which T is which value

if you think from the perspective of the car, we're told in the problem that 50 minutes elapses on the ship, so t=50, and we solve for To which is about 40.

It's too late for me think about if that's right, but...it is, isn't it? Since the car is moving .6c relative to the ship, it's ticking slow, if you will

but shouldn't you be able to do it the other way, from the perspective of the ship? So To=50 and solve for T which is like 62.5 and my head thusly explodes
