Work Energy Problem

    1. The problem statement, all variables and given/known data

    Juana slides a crate along the floor of the moving van. The coefficient of kinetic friction between the crate and the van floor is 0.120. The crate has a mass of 59.1 kg and Juana pushes with a horizontal force of 111 N. If 73.3 J of total work are done on the crate, how far along the van floor does it move?


    2. Relevant equations


    3. The attempt at a solution

    How does static friction fit into this equation? I know this is a work problem but I am just confused as to how I put static friction into the equation.

    Its kinetic friction, not static since the crate is moving. You misread the question.
