1. The problem statement, all variables and given/known data A horizontal applied force, F, pulls a 21 kg carton across the floor at constant speed. If the coefficient of kinetic friction between the carton and the floor is 0.41, how much work does the applied force do in moving the carton 2.5 m? 2. Relevant equations I'm supposed to be working with energy techniques, we just covered work/power/energy conservation/and so on 3. The attempt at a solution I don't quite understand, it seems to me like the force is 0 given there is no acceleration.
