Question

A 4.0 N crate rests on a rough horizontal floor. A 12N force is then applied to it. If the coefficients of friction are us=0.5 and uk=0.4, the magnitude of frictional force on the crate is
?

Answer 1

Answer:

1.6 N

Explanation:

The applied force is more than static friction and hence crate will move and so then kinetic friction will act.
