Homework Statement A uniform disk (like a record turntable) turns with a frequency of 5.2 rev/s around a frictionless spindle. A non-rotating rod of the same mass as the disk and length equal to the disk's diameter is placed on the freely spinning disk so both turn around the spindle. (Idisk...

I can't believe I made such a stupid mistake. Thanks.

Homework Statement A particle p traveling with a speed of vpi = 3 m/s hits and scatters elastically from another particle N, initially at rest. Particle p is deflected through 90°, leaving with a speed of vpf = 2.3 m/s, and a mass mp = 2 kg. a) What angle (in degrees) does the recoiling N...

Homework Statement a. The Hermes experiment is a fixed target experiment. The HERA accelerator creates circulating beams of electrons of energy 27 GeV; these are repeatedly crashed into a target of protons which are at rest. What is the center of mass energy of the electron-proton...

Homework Statement Use the first order Taylor approximation (1 + \epsilon)n \approx 1 + n\epsilon for \epsilon<<1 to see what the particle's speed v(t) is in the non-relativistic limit of small speeds. The specific approximation you'll want to make is that the dimensionless quantity...
