7. Fig. 114. At 0 we have the sphere in its initialposition, the forces acting on it being itsown weight G (a resistaiice), and the twocomponents, i\^and T, of the pressure ofthe inclined plane against it. Since thereis no slipping (i.e., perfect rolling), both ]Vand T are neutral (see § 84). Let… … Fig. 114. The initial K. E. of translation isGo^? and kj = I ioD^IIk;.
