Answer: The magnitude of the pony's velocity is 16 km/h.

Explanation:

Mass of the pony express = 450 kg

Momentum of the pony express = 7200 kg km/h

[tex]Momentum=Mass\times Velocity[/tex]

[tex]7200 kg km/h=450 kg\times Velocity[/tex]

[tex]Velocity=16 km/h[/tex]

The magnitude of the pony's velocity is 16 km/h.
