    Collision Momentum
AI Thread Summary
In head-on collisions, the damage is significantly greater when individuals rebound rather than stick together due to the principles of impulse and change in momentum. When two people collide and rebound, they experience a second impact, increasing the overall force and energy transfer. Momentum conservation plays a critical role, as it dictates that the total momentum before and after the collision remains constant. The rebound leads to additional momentum changes, resulting in greater damage. Understanding these dynamics is essential for analyzing the effects of collisions on individuals.

Homework Statement


Consider a head-on collision between two people. The damage done to each person is far greater if the people rebound upon impact versus sticking together upon impact. Why? Discuss in terms of impulse/change in momentum.


Homework Equations


Momentum = (mass x Volume of 1st person)(Massx Volume of second person)


The Attempt at a Solution



I'm pretty lost.

You have been doing work on collisions in class.
What conservation law do you normally use?
 
That Momentum is always conserved
 
If they rebound then they will encounter a second collision with the floor.

Fine - so how would you normally use this law?
 

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 '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...
