1. Understand the Concepts

* Force (F): The push or pull on an object. Measured in Newtons (N).

* Acceleration (a): The rate of change of velocity. Measured in meters per second squared (m/s²).

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

* Newton's Second Law of Motion: F = m * a (Force equals mass times acceleration)

2. Identify the Given Information

* Force (F) = 6600 N

* Initial velocity (v₀) = 0 m/s (since it starts from rest)

* Acceleration (a) = 170 m/s²

* Time (t) = 2.3 seconds

3. Apply Newton's Second Law

We need to find the mass (m). Rearranging the formula:

m = F / a

4. Calculate the Mass

m = 6600 N / 170 m/s²

m ≈ 38.8 kg

Therefore, the mass of the object is approximately 38.8 kg.
