Woops, saw what I did wrong there & Got the right answer immediately. Thanks a lot!

What am I doing wrong here? t' = t*sqrt(1-v^2/c^2) t' = 100000*sqrt(1-0.9c^2/c^2) t' = 31622.7766

Managed to solve both 2 and 3 now

As always, I have trouble getting started and getting my head around what to do and how. Some small tips to get started would be appreciated.

Hi guys and girls. Need some assistance with these problems, not the hardest examples, but I need some help on the way. Homework Statement 1. An astronaut travels at 0.9c across our galaxy, which is 100 000 light years in diameter. How long time will it take (according to the...

The whole thing looks like this: http://pici.se/pictures/mnClqYBkT.jpg The end is at the same height as the point where the velocity of the ball is 2.16 m/s

My physics teacher gave us this follow-up to the classic loop-de-loop assignment where you have to calculate the height from where you have to drop a ball in order for it to just make it round the loop. The problem with this assignment is that our teacher refuses to help us, and there are no...
