Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to have some help the following problem

If a 32 g arrow moving at 160km/h penetrates a block of wood suspended by a rope, what is the impulse is delivered to the block?

The impulse= momentum_{final}-momentum_{initial}.

We know that momentum_{initial}= 0.32 kg* 44.44m/s=14,28 N.

But what is the momentum_{final}??

I do not understand this concept well even after read the texbook. Can someone explain me what is going on ?

Thank you

B
