Normally a lightly loaded airliner needs about 30 seconds to accelerate to about 150 kts (I know, that performance is already on the optimistic side).
I recall from many years ago, my company asked its crews ti time how long it took to get to 100 knots (nil wind) in a 737-200 at varying weights at ISA +10 sea level. About 50 take off's were measured. In all cases it was between 40-45 seconds and it turned out as quite a useful acceleration check. 30 seconds to reach 150 knots would require an afterburner and 737's don't come equipped with one of those.
