Understanding Momentum

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

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

Calculations

* Mass (m): 725 kg

* Velocity (v): 30 m/s

* Momentum (p) = (725 kg) × (30 m/s) = 21,750 kg·m/s

Answer: The momentum of the compact car is 21,750 kg·m/s.
