    Gun Mass Shell
AI Thread Summary
The discussion focuses on the physics of a gun firing a shell and the resulting recoil of the barrel. It seeks to determine the recoil speed of the barrel when the shell is fired horizontally and when it is inclined at an angle A. Participants emphasize the importance of using a homework template to clarify the problem statement and equations involved. The conversation highlights the need for a structured approach to solving the problem, including relevant physics principles. Overall, the thread aims to facilitate understanding of the dynamics involved in the firing of a projectile and its effects on the gun's motion.

Member advised to use the homework template and to show an attempt at solution!
A gun of mass M fires a shell of mass m and recoils horizontally.
If the shell travels with speed v relative to the barrel,
find the speed with which the barrel begins to recoil if
(a) the barrel is horizontal
(b) the barrel is inclined at an angle A to the horizontal.

Hello jpc, welcome to PF :smile: !

If your post wasn't moved here from another forum, you must have seen the homework template flash by. And deleted it by accident. It is very useful however, and even mandatory in these PF forums. So indulge us and complete your post, please.

The problem statement looks OK. Now the remainder:

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
