Calculating Linear Momentum of Flag-Pole/Bird System

AI Thread Summary
To calculate the linear momentum of the flag-pole and bird system, one must consider the combined mass of both the bird and the flag-pole after the collision. The initial momentum of the bird can be determined using its mass and velocity before impact. Since the bird becomes stuck to the flag-pole, the system's momentum can be calculated using the conservation of momentum principle. The type of flag-pole may influence the outcome, particularly regarding its ability to trip and the resulting motion. Ultimately, linear momentum is applicable in this scenario despite the complexities introduced by the collision.

Homework Statement


If I have a bird that flies into a flag-pole with velocity x m/s, and the flag-pole trips, how do I find the linear momentum of the flag-pole/bird system? (The bird gets stuck to the flag-pole).

The Attempt at a Solution


I know how to find the angular momentum, but does it even make sense to talk about linear momentum in this case?

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'

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'

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...
