Answer:
240 Ns
Explanation:
The momentum of an object is the product of its mass and its velocity:
[tex]p=mv[/tex]
where m is the mass of the object and v its velocity.
According to Newton's second Law of motion, the change in momentum of an object is related to the force applied by it by the equation:
[tex]F=\frac{\Delta p}{\Delta t}[/tex]
where
F is the force exerted on the object
[tex]\Delta p[/tex] is the change in momentum
[tex]\Delta t[/tex] is the time elapsed
In this problem:
F = 120 N is the force exerted on the object
[tex]\Delta t=2 s[/tex] is the time elapsed
Therefore, the change in momentum of the object is:
[tex]\Delta p=F\Delta t=(120)(2)=240 Ns[/tex]
