Answer 2

Given that,

Mass of the object, m = 3 kg

Impulse, J = 15 N-s

To find,

The magnitude of the object's change in momentum due to this impulse.

Solution,

The change in momentum of an object is equal to its impulse. It is given by :

$J=m(v-u)$

u and v are initial and final velocities

It is clear form the above definition that the change in momentum due to this impulse is equal to 15 N-s.
