Hi,
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
