Given:
Mass of dog = 1.5 kg
velocity = 5 m/s
Let's find the momentum, mass and velocity.
To find the momentum, apply the formula:

Where:
p is the momentum
m is the mass
v is the velocity
From the question, we have:
mass = 1.5 kg
velocity = 5 m/s
To find the momentum, we have:
![\begin{gathered} p=mv \\ \\ p=1.5\operatorname{kg}*5\text{ m/s} \\ \\ p=7.5\operatorname{kg}.m\text{ /s} \end{gathered}]()
Therefore, the momentum of the dog is 7.5 kg.m/s
ANSWER:
• Momentum = 7.5 kg.m/s
,
• Mass = 1.5 kg
,
• velocity = 5 m/s
