LA force of 42 N is needed to start a box sliding across the floor. The weight of the box is 55 N Draw all the forces acting on the box. a How large is the force of friction? F-fmax 0 fmax=f F-f-0 42N-f%-0 fmax:42N Answer bIs the frictional force static or kinetic? The frictional force is static becouse the force given to the box is the some as STarting the motion from a standstill. hence the friction force is the same as static friction force.
