Homework Statement
Spacecraft moving at 0.6c, length 180m with someone sitting at the back. He throws a cage with a mouse towards the front also at a speed of 0.6c. A stationary observer watches.
Homework Equations
What is length of spacecraft from observers POV? Length according to guy sitting at back? Length according to little mouse? How long does it take for cage to reach fron of ship according to mouse and observer? How fast (according to observer) does mouse travel
The Attempt at a Solution
According to Galilean velocity, I would say speed according to observer was 1.2c. However, as this is not possible then my answer would be c.
The length according to observer would be 144m ie 180 m x sq route of (1 - v^2/c^2)
Struggling to work out time/length as seen by mouse and how long it takes for mouse to reach the front.
Cheers
