Understanding the Concepts

* Newton (N): The unit of force.

* Mass (kg): The amount of matter in an object.

* Acceleration due to gravity (g): The acceleration experienced by objects near the Earth's surface, approximately 9.8 m/s².

* Force (F): The product of mass (m) and acceleration (a): F = m * a

Calculation

1. Formula: We can use the formula F = m * a to find the mass (m).

2. Rearrange the formula: To solve for mass, we get: m = F / a

3. Substitute values:

* F = 98.1 N

* a = 9.8 m/s²

* m = 98.1 N / 9.8 m/s²

4. Calculate: m = 10 kg

Answer: The mass of the 98.1 Newton block is 10 kg.
