The final momentum is 20.00 kg*m/s

Explanation:

The momentum of an object is given by:

$p=mv$

where

m is the mass of the object

v is its velocity

For the object in the problem, the initial momentum is

$p=mv=5.00 kg m/s$

Then, the mass is doubled:

m' = 2m

And the velocity is also doubled:

v' = 2v

So, the new momentum will be:

$p'=m'v'=(2m)(2v)=4(mv) = 4p = 4(5.00)=20 kg m/s$

So, the final momentum is 4 times the initial momentum.
