Answer to Question #256547 in Mechanics | Relativity for brayden

Question

The force of friction between an object and the surface upon which it is sliding is 46N and the coefficient of friction between them is 0.30. What is the weight of the object?

Answer 1

From the third law of solid friction

Friction = βR

R is the normal reaction

$R = \frac{Friction}{β} \\ R = \frac{46}{0.30} = 153.33 \;N \\ R=mg$

mg is the weight

So,

Weight W = 153.33 N
