Aphysics 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?

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

and Friction force is

where N is the normal reaction

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

increase masses, decrease separation
