Question

12 formula 1 point a book has a mass of 0.7 kilograms and sits still on a flat table. calculate the normal force acting on the book from the table. answer previous

Explanation:

Step1: Recall the formula for weight

The weight \( W \) of an object is given by \( W = mg \), where \( m \) is the mass and \( g \) is the acceleration due to gravity (approximately \( 9.8 \, \text{m/s}^2 \)). For a book at rest on a flat table, the normal force \( F_N \) from the table on the book is equal to the weight of the book (Newton's third law and equilibrium).

Step2: Calculate the normal force

Given \( m = 0.7 \, \text{kg} \) and \( g = 9.8 \, \text{m/s}^2 \), we calculate \( F_N = mg \).

$$ F_N = 0.7 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 6.86 \, \text{N} $$

Answer:

\( 6.86 \, \text{Newtons} \) (or \( 6.86 \, \text{N} \))
