Answer to Question #30822 in Mechanics | Relativity for Akhila

A round cone A of mass 3.2 kg and half-angle alpha equal to 60 deg. rolls uniformly and wihout slipping along a round conical surface B so that its apex o remaining stationary . The centre of gravity of cone A is at the distance lequal to 17cm from it. The cone's axis moves with angular velocity w(omega). Find
(a) statc friction force acting on the cone A if w(omega) equals to 1.0 rad/sec
(b) at what values of w(omega) the cone A will roll without sliding, if the coefficient of friction between the surfaces is equal to k
k equal to 0.25
