When you try to walk too fast on a slippery floor, you slip because walking fast requires you to exert a greater frictional force against the floor than the surface allows. What is the maximum frictional force you can exert against the floor with one foot that bears your full weight of 555 N, if μs = 0.19?

Answer 1

You will find the answer by writing down the definition of μs, and setting it equal to 0.19

(max friction force)/weight = μs = 0.19
