I'm stuck here. Does anyone have a suggestion?

Ok, I see. Thanks for your help! I'll mark this as solved now.

I'm curious about how you used mesh current analysis in this problem. Would you mind describing it to me?

I think I've found a solution to this problem, but I'm still not convinced about how the currents flow in this circuit configuration. My solution: Point 1 obviously has the potential 7V. The node beneath the 15 ohm resistance, which I call V_3, has the potential -6V. The voltage over the 15...

I see. Thanks! You've made it a lot clearer. I'll post again if I need more help.

Ok, but is the expression (deltaKE)^2 = <KE^2> valid? If so, can I just take the square root to get the mean KE?

I don't think I quite understand. Did you, as I did, derive the expression for the KE from KE = p^2/(2m) ? I simply substituted p with deltap to get the min deviation in KE. I'm not sure how I am supposed use the expression of H.
