In 1916 Milikan used measurements of the kinetic energy of photoelectrons to detemine plancks constant. In order to understand how he did this, use this equation K=hv-? (where ? equals the binding energy before the electron was ejected) to determine the slope of the photoelectron kinetic energy, K, with respect to photon frequency.
Billiard ball A of mass = 0.130 moving with speed = 2.80 strikes ball B, initially at rest, of mass = 0.150. Consequently of the collision, ball A is deflected off at an angle of 28.0 with the speed = 2.00.
