floor. The coefficients of static and kinetic friction are 0.5 and 0.3, respectively. The

worker pulls with a force of 40 N. The frictional force exerted by the surface is...??

the box is moving because fk<fs

If the Fnet is not 50N, the applied force then

Fnet= T - fk

Fnet= 50N - fk

and of cource fk= .3 * 10 * 9.8 = 29.4N

Is this right??
