Chapter 3, Problem 3/234(choose chapter or problem)
A particle moves on the inside surface of a smooth conical shell and is given an initial velocity \(\mathbf{v}_{0}\) tangent to the horizontal rim of the surface at A. As the particle slides past point B, a distance z below A, its velocity v makes an angle \(\theta\) with the horizontal tangent to the surface through B. Determine expressions for \(\theta\) and the speed v.
