What is the acceleration of a learjet?

Question

What does it go 0 to ???, in ??? seconds.

Answer 1

These figures don't really mean anything in regard to airplanes.  Performance figures for aircraft are given in terms of the ground roll required for a takeoff, the maximum speed in level flight, and the cruising speeds under various conditions.

An airplane is not a dragster, and will not compete with an automobile.

If you want to learn about performance figures for airplanes, try an internet search on "aircraft performance."  You will find lots of information.

Answer 2

That's a question like "how long is a rope?"  It depends on many factors. Weight, temperature, altitude. It's also information that does you absolutely no good.
