Question

A physics major is cooking breakfast when he notices that the frictional force between his steel spatula and his Teflon frying pan is only 0.200 N. Knowing the coefficient of kinetic friction between the two materials, he quickly calculates the normal force. What is it?

Answer 1

Answer:5 N

Explanation:

Given

A physics major is cooking breakfast when he notices that the frictional force between his steel spatula and his Teflon frying pan is only 0.200 N

And from tables of coefficient of Kinetic friction for Teflon is $\nu _k=0.04$

and Friction force is $\nu N$

where N is the normal reaction

$N=\frac{0.200}{0.04}=5 N$

Answer 2

Based on the data provided, the normal reaction is 5N.

What is frictional force?

Frictional force is the force which acts between two surfaces in contact, opposing the relative motion of one surface over the other.

The frictional force F, normal reaction R and coefficient of friction U is given by the formula:

• U = F/R

From the above formula;

R = F /U

The coefficient of kinetic friction of Teflon = 0.04

R = 0.2/0.04

R = 5 N

Therefore, the normal reaction is 5N.
