Compare the de Broglie wavelength of a golf ball moving at 70.0 miles per hour (31.3 m/s) to that of a proton moving at 1.30E7 miles per hour (5.81E6 m/s) and an alpha particle with a speed of 3.40E7 miles per hour (1.52E7 m/s)?

The de Broglie equation is...

wavelength = Planck's constant/mass * velocity

I do not know what a standard golf ball masses, but this is merely a plug and chug problem once you have the proper masses.  ( Which I am too lazy to look up! )
