Question

Книга тисне на стіл із силою 4 Н. Яка маса книги? (g=10Н/кг)

Answer 1

F = mg => m = F/g = 4/10 = 0.4 (кг)

Answer 2

Calculation of the Mass of the Book

To calculate the mass of the book, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In this case, the force exerted on the book is 4 N, and the acceleration due to gravity is 10 N/kg.

Using the formula:

Force = Mass x Acceleration

We can rearrange the formula to solve for mass:

Mass = Force / Acceleration

Substituting the given values:

Mass = 4 N / 10 N/kg

Simplifying the equation:

Mass = 0.4 kg

Therefore, the mass of the book is 0.4 kg.
