Answer:
10,000 kg m/s
Explanation:
The impulse exerted on an object is equal to the change in momentum of the object itself:
[tex]I=F \Delta t = \Delta p[/tex]
where
I is the impulse
F is the force applied
[tex]\Delta t[/tex] is the time during which the force has been applied
[tex]\Delta p[/tex] is the change in momentum
In this problem, we are already given the change in momentum of the rocket: since the rocket starts from rest, its change in momentum is equal to its momentum after 5 seconds,
[tex]\Delta p = 10,000 kg m/s[/tex]
and so, the impulse is equal to this value.
