Here's how to calculate the momentum of the object:

Understanding Momentum

Momentum is a measure of an object's mass in motion. It's calculated as:

* Momentum (p) = mass (m) × velocity (v)

Calculation

* mass (m) = 25 kg

* velocity (v) = 4 m/s

* Momentum (p) = 25 kg × 4 m/s = 100 kg m/s

Answer: The momentum of the 25 kg object going 4 m/s is 100 kg m/s.
