If your go-cart weighs 500 kiligrams what is the force you will have to apply to accelerate it at plus 1.5 miles per second per second?

1.5 miles per second2 is 246 G's.

In order to accelerate it at that rate, you'd have to push it with a force that's

246 times as much as it weighs, and I'd suggest that you don't do that while

anybody is sitting in it.
