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

Step-by-step 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
`\\u _k=0.04`

and Friction force is
`\\u N`

where N is the normal reaction

`N=(0.200)/(0.04)=5 N`
