Momentum Formula

Momentum (p) is calculated using the following formula:

p = mv

where:

* p = momentum (measured in kg·m/s)

* m = mass (measured in kg)

* v = velocity (measured in m/s)

Applying the Information

* Mass (m) = 30 kg

* Velocity (v) = 2 m/s

Calculation

p = (30 kg) * (2 m/s) = 60 kg·m/s

Answer

The magnitude of the dog's momentum is 60 kg·m/s.
