Here's how to solve this problem using Newton's Second Law of Motion:

Newton's Second Law:

* F = m * a

Where:

* F is the force (in Newtons, N)

* m is the mass (in kilograms, kg)

* a is the acceleration (in meters per second squared, m/s²)

Given:

* Force (F) = 30 N

* Acceleration (a) = 5 m/s²

Finding the Mass (m):

1. Rearrange the formula to solve for mass: m = F / a

2. Substitute the given values: m = 30 N / 5 m/s²

3. Calculate the mass: m = 6 kg

Therefore, the mass of the object is 6 kg.
