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:


p=mv

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
