An electric motor rotating a workshop grinding wheel at a rate of 9.80 x 101 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 2.20 rad/s2. (a) How long does it take for the grinding wheel to stop?
You send a beam of light from a material with index of refraction 1.23 into an unkown material. In order to help identify this material, you determine its index of refraction by measuring the angles of incidence and refraction for which you find t
