How about a massive catapult to replace the space shuttle

The poster suggested using a giant catapult to put things in space instead of rockets. Maybe he or she was kidding, or maybe not. But I have heard this idea before. Would it work? First, how do things ... determine the average force exerted on the ...How High Can You Toss Your Phone?

Now, if you know the acceleration (you do) and you know the time the object is in the air with this acceleration (you do since it is recorded from the phone) then you can find the ... time interval h.
