Question

Please Solve using angular momentum

Mass in Cone. Masses A and each of mass m, are attached at the ends of a string that runs through the small hole in the center of a cone, for which θ-60° (a) If ball B is hanging a constant distance below the cone and ball A is moving in a horizontal cir- cle with constant speed vo, de- termine, as a function of vo and Neglect friction between A and the cone and between the string and the hole. Use cos θ-1 and sin θ- g, the distance L. 2 (b) Now a force P, which increases from zero to a constant value, is applied to B to pull it down a distance L/2 and it is then held at that position. When B is in this position and A is moving irn a new circular path, determine the speed of A as a function of 0 Extra Credit: Determine, as a func- tion of m and vo, the work done by P in moving B to its new position.
