Here's how to calculate the magnitude of the baby cow's momentum:

Understanding Momentum

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

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

Applying the Information

* Mass (m) = 100 kg

* Velocity (v) = 0.5 m/s

Calculation

* Momentum (p) = 100 kg × 0.5 m/s = 50 kg m/s

Answer

The magnitude of the baby cow's momentum is 50 kg m/s.
