1. The problem statement, all variables and given/known data A 50 kg box is being pushed up an incline of 25 degrees, to a total height of 45 m. Kinetic friction between the box and the incline has a mew of .4. a) What is the work done by gravity? b)What is the work done by friction? c) What is the work done by the person pushing the box. 2. Relevant equations W = Fd 3. The attempt at a solution For all of the parts, I am not sure what to use as my d. Do I use 45, or do i use (45/sin(45)), the hypotenuse and the distance that the box actually slides?
