"At some point, usually between 15 to 20 km (9-12 miles or 48,000-63,000 feet) altitude, the meteoroid remnants will decelerate to the point that the ablation process stops, and visible light is no longer generated. This occurs at a speed of about 2-4 km/sec (4500-9000 mph). From that point onward, the stones will rapidly decelerate further until they are falling at their terminal velocity, which will generally be somewhere between 0.1 and 0.2 km/sec (200 mph to 400 mph). Moving at these rapid speeds, the meteorite(s) will be essentially invisible during this final “dark flight” portion of their fall."
just btw, 25 km/s is almost 100.000 km/h.

One they get big enough, they slow down from ludicrously fast to still ludicrously fast. The smallest impactor shown in that table enters at 17 km/s, loses 90% of its energy traversing the atmosphere and smacks the ground at nearly 5km/s. You'll probably want to take your titanium armour and stand somewhere else.
But the if a small meteorite (only a few grams) were traveling that slow, 1.5 inches of titanium would do quite a bit.
