--description--

A firecracker explodes at a height of 100 m above level ground. It breaks into a large number of very small fragments, which move in every direction; all of them have the same initial velocity of 20 \frac{\text{m}}{\text{s}}.

We assume that the fragments move without air resistance, in a uniform gravitational field with g=9.81 \frac{\text{m}}{\text{s}^2}.

Find the volume (in \text{m}^3) of the region through which the fragments move before reaching the ground. Give your answer rounded to four decimal places.

--hints--

firecracker() should return 1856532.8455.

assert.strictEqual(firecracker(), 1856532.8455);

--seed--

--seed-contents--

function firecracker() {

  return true;
}

firecracker();
