Frictional forces [SOLVED] 1. The problem statement, all variables and given/known data A stockroom worker pushes a box with mass 11,2 kilograms on a horizontal surface with a constant speed of 3.5 m/s. The coeffisient of kinetic fricion between the box and the surface is 0.2. In a) i had to find the force that the worker must apply to maintain the motion. b) If the force calculated in part a) is removed, how far does the box slide before coming to rest. 2. Relevant equations 3. The attempt at a solution I am pretty sure that I solved task a). I found the frictionforce to be 22N, and since the box is having a constant speed, the sum of forces in x-direction have to be zero. Force = Frictionforce in this case. But i really need some tips on the B part. Anyone? Thanks!
