Homework Statement
We have the equation for gravity due to the acceleration a = -GM/r2, calculate velocity and position dependent on time and show that v/x = √2GM/r03⋅(r/r0-1)
Homework Equations
x(t = 0) = x0 and v(t = 0) = 0
The Attempt at a Solution
v = -GM∫1/r2 dt
v = dr/dt
v2 = -GM∫1/r2...
Thank you for all your help.
Well.. a massless particle should have the speed of light of course. - . -
You don't have any idea how to calculate the mass for K+ ?
Well everything if I'm going to be honest. But okey..
1. Relativistic formulas:
E2 = p2c2 + m2c4
E2 - p2 = m2
The difinition of of kinetic energy is the total energy E minus the rest energy, giving us this:
Ek = √(p2c2+m2c4) - mc2
Where the mass and kinetic energy are for the μ+. But can I...
Homework Statement
I have the decay
K+ → μ+ + νμ
Calculate:
1. Momentum of μ+
2. Total energy of νμ
3. Mass of K+
4. Speed of μ+
5. Speed of νμ
Homework Equations
The only thing we get are the kinetic energy of μ+ so Kμ+ = 152.53 MeV
and the mass of mμ+ = 105.658 MeV/c2

Thank you, now I understand that part.
What will the degeneracy become for the 1st excited state then? Can I use the same formula gn = 1/2(n+1)(n+2) for this case?
Can you elaborate on that? Is 4y2 just n2 here? And in that case you will get three different energy values:
E100 = 3hw1/2
E010 =6hw2
E001 =3hw3/2
Which one is the 1st excited state? Is it E010?
Hi,
For a harmonic oscillator in 3D the energy level becomes En = hw(n+3/2) (Note: h = h_bar and n = nx+ny+nz) If I then want the 1st excited state it could be (1,0,0), (0,1,0) and (0,0,1) for x, y and z.
But what happens if for example y has a different value from the beginning? Like this...
