How is Impulse Calculated in a Collision with Changing Velocities?

AI Thread Summary
The discussion revolves around calculating impulse in collisions with changing velocities, using two specific problems as examples. The first problem involves an aircraft that changes velocity after a meteor strike, while the second concerns a perfectly elastic collision between two balls. Participants emphasize the importance of showing effort in problem-solving before seeking help, as per forum guidelines. They encourage the use of the impulse equation I=m(V2-V1) to approach the first problem and clarify the expression of velocities. Overall, the thread highlights the need for proper problem setup and understanding of fundamental physics concepts in collision scenarios.

Homework Statement


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 ?

Homework Equations


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

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.

okay,, I'm first in PF and I'm sorry for that. I will change my post.

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?

I=m(V2-V1)

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

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
