Hi , im trying to practice working with new exercises and i've met some problems.

Lifting object with mass of 2kg to height of 10m we do 240J mechanical work.

What is acceleration of lifting?

My calculations:

A=Fs=Fh

F=A/h = 240/10 = 24N

a= F/m = 24/2 = 12 m/s^2 , somehow it's not the right answer
