How Can Two Bullets Fired from the Same Rifle Collide Midair?

[feb2_sg]

Hi!

I have been trying to figure out this problem for hours now. If I want two bullets discharging from the same rifle to collide in midair with just a change in the angle of elevation. Can you show the time interval needed? I think that this question is interesting enough to be posted. Thanks.

According to the rules of the forum I will post my own attempts to solve this problem. What I have done so far is write down the projectile motion equations, say that their final position must be equal for a collision to happen and of course the acceleration vectors. These does not seem to be enough. Any suggestions would be appreciated.

Hint: The condition for a collision is for position (horizontal and vertical) to be equal for both bullets at the same time. Give us your equations of motion and we'll try to help you.

Excellent. I think that I would find this place to be very helpful indeed. By the way, what software do you guys use to post equations on the board? I am thinking of using Maple 10? Or do you guys have a standard? ;p

By the way, I appreciate the help. The homework has been handed in but I would still like to hear from someone. I am taking 4 physics courses and frankly, I am a little nervous. But if I pass this semester, I am virtually guaranteed to be ok for the rest of the year. This is definitely a critical point for me.. ;p

I am going to be posting the equations really soon. Say, is anyone here studying Quantum Mechanics? I am in my introductory course.

I guess the equations will have to wait. I am working on my Optics homework and won't be done for a while. It is encouraging that people are finding this thread interesting enough to read it.

Forget it. I am so swarmed with work right now I just can't be adamant on solving every question that comes my way.
