AI Thread Summary
The discussion revolves around a physics problem involving a pigeon flying between two cars moving toward each other. The cars are initially 400 meters apart, traveling at speeds of 16 km/h and 25 km/h. The main questions are how long it will take for the cars to collide and the total distance the pigeon will fly before the collision occurs. Additionally, there is a query about calculating the "net distance" from the pigeon's starting position to the collision point. The problem emphasizes the motion equations needed to solve these questions.

The pigeon is doing exactly what the problem says- flying back and forth between the two cars at 36 km/h. Meanwhile, the two cars are moving toward each other at 16 and 25 km/h. The cars are initially 400m apart. How long will it take them to crash together? (Of course, the pigeon, always being between the two cars will be killed in the collision but try not mourn too long!) In that time how far (total distance) will the pigeon have flown? The second part of the question is a little harder- what is the "net distance", that is the distance from the pigeon initial position, on the first car which is driving at 16 km/h to the point where the two cars collide.
 
ok thanks I will think later and then tell the answer
 

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...
