The final momentum is 20.00 kg*m/s
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 the problem, the initial momentum is
[tex]p=mv=5.00 kg m/s[/tex]
Then, the mass is doubled:
m' = 2m
And the velocity is also doubled:
v' = 2v
So, the new momentum will be:
[tex]p'=m'v'=(2m)(2v)=4(mv) = 4p = 4(5.00)=20 kg m/s[/tex]
So, the final momentum is 4 times the initial momentum.
