A constant applied force ?pFp of 15.0 N15.0 N pushes a box with a mass ?=7.00 kgm=7.00 kg a distance ?=15.0 mx=15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is 0.150. Assuming that the box starts from rest, what is the final velocity ?fvf of the box at the 15.0 m15.0 m point? If there were no friction between the box and the floor, what applied force ?newFnew would give the box the same final velocity?
