Faster every hit

What we are doing

Long rallies get exciting when the ball speeds up: every hit makes it 5% faster, up to a limit of 12.

```js
const speed = Math.min(Math.abs(ball.vx) * 1.05, 12)
```

What it means

• * 1.05 makes the speed 5% bigger each hit.
• Math.min(..., 12) takes the smaller of the two, so the speed never goes past 12.

Your turn

In bounceOff, change the speed line.
