I don't believe force has anything to do with this problem? It only asks for work, I got an answer of 60.0 J.

I'm not any expert but I think using the Work Energy Theorem will quickly give you an answer for work. I think your mass of Jeff + Toboggan was correct. Work = KE_{f}-KE_{i} = \frac{1}{2}mv_{f}^{2}-\frac{1}{2}mv_{i}^{2} Hope this helps. Good luck on the MCAT! Someone correct me if I'm wrong.

Could we not say this occurs when the vertical component of velocity is zero?

Please forgive me if the answer to this question is obvious, I studied Political Science for three years in undergrad before I realized 'real' science was far more rewarding. My question (not homework): I understand that Work-Energy can be used for projectile motion, if what you're after is...
