Question

How does the momentum of a dog and a horse, which are both running at the same velocity, compare?

Answer 1

The horse has a greater momentum.

Answer 2

Answer: The momentum of horse will be more than the momentum of dog.

Step-by-step explanation:

Let the momentum of dog and horse be
`P_d` and
`P_h`

Mass of the dog =
`M_d`

Mass of the horse =
`M_h`

Given that velocity with which dog is running is equal to the velocity with which horse is running.

`V_d=V_h=V`

`Momentum=\text{mass of the body}* \text{velocity of body}=P=MV`

`P_d=M_d* V`..(1)

`P_h=M_h* V`..(2)

From (1) and(2) we can say that
`P_d<P_h`

Since,the mass of horse is larger than the mass of the dog the momentum of the horse will be more than the momentum of the dog.
