How does he know the initial velocity of the incoming croquet ball. It is not listed in the problem statemt. Two equations, three unknowns. Unknowns v_{1_{initial}} v_{1_{final}} m_{2}

I am attempting to solve a second order differential, but I am have never done anything like this. I was told that it was a good Idea to think about Fourier transforms. \frac{d^{2}q}{dx^{2}}=\frac{dq}{dt} Boundary Conditions: q(+/-\infty,t)=0 q(x,0)=S_{0}\delta(x) Apparently the final...

Thank You, That is exactly what I was missing.

Your right, this is basically compton scattering without the relativisitic effects. That is why the first 4 steps are the same as the Compton Scattering derivation. The difference is that the since this does not use relativistic effects: E=\frac{p^{2}}{2m} For Compton Scattering, the...

4*\pi*r^{2} is the surface area of a sphere. If the plate is a certain distance away, you can simply assume the the source is emitting isotropically. Divide the surface area of the plate by the spherical surface area (r= the distance from the plate). This will tell you what percentage of your...

I am pretty sure that the answer is 15J. Lets try it with numbers (although they don't really matter.) Let's say the bulldozer applies 5 Newtons for 3 Meters (3*5=15). This means that if the rock was not present, it would take 15 Joules less to move those 3 Meters. You can think of this -15J...

Can Someone look over this and tell me if the work is correct. Homework Statement An object comes in with known velocity (v) and known mass (m) moving directly along the x-axis. It strikes another object of the same mass (m) which is stationary. Find the change in energy of the incoming...

Rutherford Scattering This problem is an exact repeat of Rutherfords attempts to test the "Plum pudding model' of the atom. For the Exact math search rutherford Equation. http://hyperphysics.phy-astr.gsu.edu/hbase/rutsca.html

Thank you, The link was incorrect, but it wasn't hard to navigate there. http://physics.nist.gov/PhysRefData/Star/Text/contents.html

The problem asks me to determine the rate of breakdown due to firing 120 kev Electrons at Titanium of arbitrary thickness. I could solve this problem if I knew The average energy deposited per electron, or the Energy efficiency of the entire beam through the titanium. Given: Electron Flux...
