Answer:
Yes
Explanation:
The momentum of an object is given by:
where
m is the mass of the object
v is the velocity of the object
We know that an elephant has a mass much larger than the mass of an ant. However, we see that the momentum of the animal also depends on its velocity.
If the elephant is at rest, its velocity is zero:
v = 0
so its momentum is also zero:
p = 0
And therefore, an ant which is moving (so, non-zero speed) can have more momentum than an elephant, if the elephant is at rest.
