Rutherford Scattering and relativistic effects

[MrDMD83]

Homework Statement

n a Rutherford scattering experiment a target nucleus has a diameter of 3.5 10-14 m. The incoming has a mass of 6.64 10-27 kg. What is the kinetic energy of an particle that has a de Broglie wavelength equal to the diameter of the target nucleus? Ignore relativistic effects.

Damn dude, here's the equation you need:

$$E=\frac{hc}{\lambda}$$
E is the energy, h is the planks constant, c (more properly v) is the speed of the particle, and lambda is the de-broglie wavelength.

E and KE are equal in this case.
