A 0.25kg arrow with a velocity of 12m/s to the west strikes and gets stuck in the center of a 6.8kg target. What is the impulse of the arrow as it hits the target?

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

i think it's 35 meters

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
