icle upon a Fixed Plane. CaseI. Smooth Contact. — Let Vt and v^, Fig. 121, be the compo-nents of the velocity along the plane and along the normal,respectively, just before the impact; and let w/ and v„ bethe corresponding components just after the impact. Sincethe plane is smooth, no hori-zontal… … ev„ Fig. 121. Denoting by. a and j3 the angles which the resultant velocitymakes with the normal just before and just after the im-pact we obtain tan a = —> v^ tan /3 = -^• :. tan a. = e tan ^. (XIV) Discussion.—When the contact is perfectly elastic e = 1; thereforethe angle of incidence equals…
