A box takes 40 N to start moving when the coefficient of static friction is .54. What is the weight of the box?
|
|
81 N
|
|
|
18 N
|
|
|
98 N
|
|
|
74 N

Explanation:
Detailed explanation-1: -Hence, weight of the box is 74.08 kg.
Detailed explanation-2: -The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N.
Detailed explanation-3: -The coefficient of static friction between a 40.0-kg picnic table and the ground below it is 0.43.
