I am stuck on this problem and I really need to figure it out or I will probably have to kill myself. Just saying. Also, I'm having the worst day of life, was fired from my job, and basically laughed at by my parents. Here is the problem: A 60kg person starts from rest and slides down the curved surface from height of 7.0 meters. If the speed at the bottom is 2.8 m/s, find how much thermal energy due to friction was generated. PLEASE HELP!!! THANK YOU IN ADVANCE.
