be able to escape Earth's gravity, and if so how long would it take to reach the moon?

And if not, how fast would he have to kick/throw you?

1400 mph would not even get you out of the atmosphere before you fell back to the ground. You need at least 25,000 mph. That would get you to the Moon in 3 days. Note that you would not be going 25,000 mph all the way, that would just be your speed right after he kicked you. You would gradually slow down all during the trip as Earth's gravity tried, unsuccessfully, to pull you back to the ground.

It's a matter of momentum exchange...
the other two are correct, if you were kicked with that speed assuminga 40 lb leg it would liquify you and you would just kind of float in pieces up into the atmosphere

You would need to acquire a velocity of 25200 miles per hour, and that would only happen if Superman's legs are 18 times heavier than you.

even assuminf a perfectly elastic collision 1400 mph would not be enough to achieve escape velocity.

The force of the blow would liquify much of your body and you would splatter as very hot goo all over his nice red boot.
your body would not remain intact.
it would be like being hit in the chest with an RPG.
