The beginning momentum of the object is zero
Explanation:
The momentum of an object is given by:
[tex]p=mv[/tex]
where
m is the mass of the object
v is its velocity
For the object in this problem, we have:
m = 3.0 kg is its mass
v = 0, because it is initially at rest, so its initial velocity is zero
Therefore, the initial momentum of the object is
[tex]p=(3.0)(0)=0[/tex]
