(adsbygoogle = window.adsbygoogle || []).push({}); 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 thechangehere is thesumof both the diss. energy from friction and gravitational potential. Since, all the kinetic gets converted to grav. potential and diss in the end.
