Kata

The kata's physics model is completely unphysical: it has no acceleration due to gravity, and instead the vertical velocity of the shot decreases by 50 / speed each tick.

The kata does not explain any information crucial to derive the result in the description. It doesn't even tell you you're supposed to calculate projectile motion. This is definitely unacceptable.

(Also, I'm pretty sure projectile motion is a duplicate)

Your initial code is wrong:

function shot( map, players, enemies )  -----------------here miss a {
  return [
    {
      angle: 10, // Angle in degree
      force: 95 // Shooting power( meters per second );
    }
  ];
{---------------------------------------------------here should be }

All heighs are in meters look like a typo?

All heights are in meters

It looks interesting, but I don't know what x and Y mean?

The other question is how to calculate the angle and power

I didn't find the answer in your Kata description ;-)

Needs some example test cases please
