1. A .25kg mass attached to a string of length 1m is spun in a horizontal circle. At what speed must it travel so that the angle the string makes with the horizontal is 30 degrees?
2. A block of mass m slides around a circular path in a conic surface with vertex angle 2theta. Determine the speed of rotation at a height h above the vertex.
Im lost at what to do for both problems. Any help would be appreciated. Thanks.
