Explanation:
Momentum is defined as the product of mass of an object and the velocity of that object.
Let [tex]m[/tex] be the mass of the object.
Let [tex]v[/tex] be the velocity of the object.
Let [tex]p[/tex] be the momentum of the object.
Given that [tex]m=0.25Kg[/tex]
[tex]v=3.5ms^{-1}[/tex]
[tex]p=mv[/tex]
[tex]p=0.25\times 3.5=0.875Kgms^{-1}[/tex]
