Newton`s Laws: Problems and Examples
... Check: When θ =0, the formulas give T=mg, and v=0. This makes sense. The ball is just hanging there. If you want it tilted at a higher angle, you have to spin it faster, and the tension in the rope increases. The case θ =90 is kind of weird. It says T and v both go to infinity. But this is formally ...
