HELP? How much force would you need to cause a 20 kilogram object to accelerate in a straight line to 20 meter per second? If you answer/answered, you helped a ton with my Physics homework :)

The question is terrible.

The acceleration of the object . . . how soon it comes up to the
speed you want . . . does depend on how much force you use.
But the final speed doesn't.

The question "How much force ?" has no answer. If you want it right now,
then you need a big force. If you're willing to wait long enough, then a fly
or a mosquito can do the job.
