I am still stuck...I don't know what equations you are referring to.haruspex said:

The discussion focuses on deriving the tangential equation of motion for a person on a waterslide with a circular curve. Key points include the need to account for both centripetal and tangential forces, as the motion is not purely circular due to the tangential component. Participants emphasize the importance of using energy conservation principles and avoiding small angle approximations unless necessary. The conversation highlights confusion over the correct application of forces and the need for clear derivations to arrive at the correct equations of motion. Ultimately, the solution involves substituting velocity in the acceleration equation and considering perturbations around an equilibrium angle.

Re-derive your acceleration equation in post #1, but this time do not make any small angle approximations. Use the energy equation to substitute for v in that.Fibo112 said:

Ok. Now use your energy equation to substitute for v2.Fibo112 said:
When you have done that, write a as the sum of the equilibrium angle and a small angle perturbation.
