So I had the correct answer to this question, and now I'm redoing it 10 minutes later and can't seem to get it correct even after using the equation in the textbook :S

\(m= 180 kg \)

\(g=9.8m/s^2\)

\({\mu}_{0} = 0.17 \)

\(a = {0.0062m}^{-2}\)

\({x}_{2}=10\)

\({x}_{1}=0\)

The textbook gives the answer of 6kJ but it rounds

The answer I got originally was something like 5997 i think.... now I get 6644.4

thanks for your help.
