[SOLVED] Mechanical Energy problem
http://img517.imageshack.us/img517/7201/dynamics3oi8.jpg
[tex]E_{m}=E_k + E_p[/tex]
I think that the answer to the problem is c), because as the object is moving up, it is slowing down because it has to work against friction and gravity. Also, as the object moves up, it gains height, and therefore gains potential energy. Am I right?
