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?(adsbygoogle = window.adsbygoogle || []).push({});

2. A block of massmslides around a circular path in a conic surface with vertex angle 2theta. Determine the speed of rotation at a heighthabove the vertex.

Im lost at what to do for both problems. Any help would be appreciated. Thanks.
