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 1

Layla Ahmed

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

#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#

The normal force is calculated by multiplying the coefficient of kinetic friction (0.03) by the gravitational force acting on the object. If the object's mass is 10 kg, the normal force would be approximately 294 N.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
