When do the spoilers go up? As soon as you land.
Yes, they are, but as they touchdown, they go immediately into reverse thrust, and slow the plane so it no longer wants to fly.
I’m sure you’ve been in an airliner when it’s bounced down the runway a couple of times as it slows (usually in a heavy cross-wind in the pilot’s defense).
The perfect example is setting up for slow flight, just above stall speed. You can fly along level at 3 knots above stall, and as soon as maybe a gust pushes you a little bit, or you let a wing drop or something, the stall horn goes off and you’ll descend a bit (granted, the stall horn goes off just above actual stall, we can discuss that, but, you get the idea). A touch of power, climb back up the few feet, let the power off again too the point you’re flying level and off you go floating through the sky.
Here, here’s another reason for your “faster than stall” question, as soon as the wheels touch, they create a ton of drag, slow the plane into stall, but you’re wheels are down. If the plane touches down at a speed so far above stall as you suggest, what happens to the plane if you don’t brake? It’ll lift off again. If you brake, you put the wings in stall. The planes that tend to bounce don’t have the brakes of airliners or CJ’s or King Airs, you’re not going to argue with that are you?
