Homework Statement Decay of particle A into three particles of equal mass, prove that the Dalitz plot is a equilateral triangle with height Q/2, inscribed within a triangle with height Q. Homework Equations Q = MassA - 3(MassB) The Attempt at a Solution For relativistic...

Pretty much. For each 100N force applied for 1 second, the decrease in velocity is 0.5m/s. In 4 seconds, -2.0 m/s decrease in velocity. Enjoy.

Thanks much.

Why don't you start by applying 100N for one second, and see what the final speed is? There is definitely a way to apply the equations, but understand it intuitively and it'll make more sense. Also, in your "F=(200kg)(2 m/s)=400 kg*m/s^2", you have an extra 1/s on the right side.

UI = u0*I, where u0 = magnetic permeability (probably of free space) and I = current.

Thanks for your response. I found that exact equation in many texts and I haven't a clue what the total inertial energy of the system is. In my particular problem, would it be E = KE(proton) + Mass(proton) + Mass(neutron)?

More work... So here's what I have so far... E* = (Ep* + En*), where Ep* = Mp + Pe En* = Mn Pe = momentum of electron in lab frame Ep* = energy of proton in CM frame En* = energy of neutron in CM frame Mn/Mp = mass of neutron/proton Is E* = Invariant mass? If so, I've got this...

I have a proton with momentum = 1GeV hitting a neutron at rest, and I'd like to find the CM-momentum before collision. Thanks

Hello, I'm working on this problem and I'd like to know how to find the invariant mass using just the lab-frame momentum and rest mass. I've found a lot of equations that deal with E, and I'm not completely sure what that is either. Thanks
