The Hare and the Tortoise 3 - Solution
Back to problem
- No, they do not agree.
The tortoise starts at B while the hare starts at H.
In the tortoise frame, B is simultaneous with G which is
chronologically later than H.
In the hare frame, H is simultaneous with C which is
chronologically later than B.
So both animals will think that the other animal started earlier than they did..
(The tortoise will not see the hare starting until it is at
D, and the hare will not see the tortoise starting until it is
at F. So if the animals do not take into account the finite time it takes
for light to reach them from their opponent's starting points, they may
reach the opposite conclusion.)
- Yes, they will agree. Both animals cross the finish line at E.
