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.

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#
