Suppose the Earth suddenly stopped.
How long time will it take until it hits the Sun ?
Please make the following assumptions:
My solution involves a lot of integration and stuff, but
the result is so simple, that I suspect there might be a
simple way of looking at the problem, that I don't know of.
The Earth's orbit is circular.
- The Sun is MUCH heavier than the Earth.
- The size of the two objects are very small compared to
the radius of the orbit.
- The only force acting on the Earth is the gravitional
attraction to the Sun.
- No relativistic effects occur.
