I have done the question already and attained the correct answer. However if it was a written question i do not know how i could prove the following.(adsbygoogle = window.adsbygoogle || []).push({});

A 7.3 x 10^3 kg space vehicle and its empty 6.8 x 10^2 booster unit are moving together through space at 370 m/s. An explosion lasting 2.2s is used to separate the two parts. If the speed of the space vehicle is increased to 430 m/s, what impulse acted on the booster unit?

I used the Impulse formula [tex] I_{space vehicle} = \Delta{p} [/tex]

And used the change of momentum of the space vehicle to determine the Impulse exerted on it. How would i prove that this impulse is the same in magnitude and opposite in direction as the impulse exerted on the booster unit?

Is their a way to do this question a different way? Did they give the time for no reason?

Regards, Senjai.
