Knowing the coefficient of kinetic friction between the two materials (0.03), he quickly calculates the normal force. What is it (in N)?

A physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Oiled Steel frying pan is only 0.450 N.

Answer:

The equation for the force of friction is F#f# = #u#FN

Explanation:

#u# stands for coefficient of friction, which in this case is 0.03.

FN is the force normal

Using the equation,

#0.450 = 0.03Fn#

#Fn = 0.450/0.03#

The force normal is therefore #15N#
