1. The problem statement, all variables and given/known data An 72.4 N box of clothes is pulled 28.8 m up a 21.8degrees ramp by a force of 117 N that points along the ramp. The acceleration of gravity is 9.81 m/s2 : If the coefficient of kinetic friction between the box and ramp is 0.27, calculate the change in the box's kinetic energy. Answer in units of J. 3. The attempt at a solution I have already figured out everything, but i'd like to know if the change here is the sum of both the diss. energy from friction and gravitational potential. Since, all the kinetic gets converted to grav. potential and diss in the end.
