Nice! All you need is a `ctx.clearRect(0, 0, w, h)` over the whole screen before you draw the ball. Either in your draw function but inside the start function is probably a better place.

Yep looks pretty good! I would make it so the draw function takes the ctx as an argument so the Ball doesn't have to rely on global variables. But that's a really minor thing.
