Homework Help Overview

The discussion revolves around a physics problem related to projectile motion, specifically concerning the initial velocity of a bullet and its behavior after being shot from a barrel. Participants are addressing the clarity of the problem statement and the implications of the initial velocity given.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants question the interpretation of the initial velocity of 630 m/s, suggesting it may be misleading. Others discuss the distinction between the bullet's velocity while in the barrel and after it exits.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem statement. There is no explicit consensus yet, but several points of clarification have been raised regarding the initial conditions of the bullet's motion.

Contextual Notes

There is an indication that the question may have been miscategorized, as it was noted that homework questions should be placed in the appropriate section of the forum.

I've just read the forum rule and fount out this is not the right place to ask school related question +_+ I'd really appreciate if any of moderators can move this question to the right h/w forum. Thank you.

This is solved.

Thank you

Regards,

well for one... the answer is not correct. If it has an initial velocity of 630... why exactly would it slow down so much? It should stay at 630m/s for the entire trip (neglecting air resistance).

oops, and homework questions MUST be put in the homework section. Please read the titles.
 
Ya I think the question is a little misleading.
I think 630 m/s is when the bullet leaves the barrel.
 
The problem statement is a bit confusing. When it says "shot with an initial velocity of 630 m/s", what they really meant to say is that the bullet has the velocity of 630 m/s after leaving the barrel. (That's the initial speed of the rest of its trajectory.)

But during its acceleration in the barrel (which is what this problem has to do with), the initial velocity is zero (that's [itex]v_0[/itex], which is given as zero) and the final velocity (within the barrel) is 630 m/s.
