50m^2!

I shouldn't try to do these while on the phone.  

If the crate exerts 2000N (mass * acceleration) it doesn't matter how big the piston is...it will still need to exert 2000N to lift the crate.

Oh ... & i didn't know you could do this via phone, lol.

stormfire1 · Answer

I got a phone call while reading your question :)

stormfire1 · Answer

Anyway, the difference in the piston size affects the force per unit area but the overall force needed to lift the crate in either case is 2000N.
