AI Thread Summary
To calculate the deuteron's velocity after a neutron collision, the conservation of momentum must be applied in both the x and y directions. The neutron's initial momentum in the x direction is equal to the combined momentum of the deuteron and the neutron after the collision. Since the neutron is deflected by 90 degrees and moves with a reduced speed, the deuteron's velocity can be determined by solving the momentum equations. The mass relationship, with the deuteron being twice the mass of the neutron, plays a crucial role in the calculations. Understanding these principles will help in deriving the deuteron's velocity components post-collision.

I'm at the last equation of my homework and I'm stuck

Homework Statement



In a nuclear reactor, a neutron moving at speed vo (vo is initial speed) in the positive x direction strikes a deuteron, which is at rest. The neutron is deflected by 90 degrees and moves off with a speed vo/*square root of three* in the positve y direction.



Homework Equations



Find the x and y components of the deuteron's velocity after the collision. The mass of the deuteron is twice the mass of the neutron.

The Attempt at a Solution



I tried, but I don't get it.
Plz help me show work if you can thxs.

what do I do because the mass in twice?
 

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...
