1. The problem statement, all variables and given/known data
1. An Aircraft Space 1000 kg moving with speed
(2000 i m / s). A meteor strikes the plane so that
speed become (2000 i + 2000 j m / s). how impulses
collision?
2. A 0.5 kg ball collides with the ball perfectly Resilience
The second is silent. The second ball away with
half speed the initial speed the ball. What percentage of the kinetic energy
transferred to the second ball ?

2. Relevant equations
1. I=m(V2-V1)
2. KE=KE'

3. The attempt at a solution

Hi and welcome to PF!

These are merely problem statements. If you read the guidelines for posting homework problems, you will find that they require you to show effort before we can help you (i.e., also fill in items #2 and #3 in the template that you used). If we do not know where you got stuck, it will be much more difficult for us to give you the appropriate help and we are not allowed to simply solve the problem for you. Instead, we will gladly point you in the right direction so that you can solve the problem yourself.

Dont worry, it is very common that this happens for first posters and your attitude to the guidelines is already better than some I have seen.

@Aprizal: Can you explain what is meant by this way of expressing the velocities?

So you now have this relevant equation. Have you tried applying this equation to your problem?
