AI Thread Summary
In the discussion about energy in collisions, the consensus is that none of the provided statements about momentum and kinetic energy conservation are true. The correct answer is e, as momentum is conserved in both elastic and inelastic collisions, while kinetic energy is only conserved in elastic collisions. It is clarified that kinetic energy is not conserved in inelastic collisions. Therefore, the initial assertion that e is the correct answer stands confirmed. Understanding these principles is crucial for analyzing different types of collisions in physics.

Homework Statement



Which of the following statements is true for collisions?
a) Momentum and Kinetic energy are always conserved in collisions.
b) Momentum can only conserved in elastic collisions.
c) Kinetic energy is conserved only in inelastic collisions.
d) Only kinetic energy can be conserved in elastic collisions.
e) None of these are true for collisions.


The Attempt at a Solution


i believe the answer is e. but thought it could be c but then momentum can also be conserved so i concluded e

Yes e is correct.

Kinetic energy is not conserved in an inelastic collision.
 

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...
