# Gone Forever

**Classical Mechanics**Level 3

I toss a stone at a velocity of \(14000 \text{ m/s}\), and an angle chosen uniformly at random from the interval \([0^\circ, 90^\circ]\), above the horizontal. What is the probability that the stone will never return to Earth?

**Details and Assumptions**:

\(g=9.8 \text { m/s}^2\), radius of Earth 6371 km.

Ignore other massive bodies, such as the sun.
