+Numerical solutions for angular velocity of ball
+
+$$
+(\dot{\omega_x})_{n+1}−(\dot{\omega_x})_n = -\frac{5}{2MR}[\mu_w \sin(\phi) + \mu_s \sin(\phi') \times (\sin(\theta) + \mu_w \sin(\phi)\cos(\theta))]\Delta P_I

+
+$`\theta`$ is a constant of the angle of cushion contact above ball centre with $`\sin(\theta) = 2/5`$. $`μ_s`$ is the coefficient of sliding friction  between the ball and table surface. $`μ_w`$ is the coefficient of sliding friction  between the ball and the cushion. 
+
+Work done by the normal force at contact point $I$ along the $Z'$-axis which is aligned from the ball centre to I
+
+$$
+W_{Z'}^I(P_I^{(n+1)}) = W_{Z'}^I(P_I^{(n)}) + \frac{\Delta P_I}{2} \left( z'_I(P_I^{(n+1)}) + z'_I(P_I^{(n)}) \right)
+$$
+
+The ball is assumed to be bouncing in the +y cushion. Compression phase iterates until 
+
+$$
+\dot{v_y} <= 0
+$$
+
+For the restitution phase the iteration continues until the work done is
+
+$$
+W_{Z'}^I >= (1 - e_e^2) W_{compression}
+$$
+
+Some of the Mathaven equations not supplied by the paper were inferred by LLMs and the [code](./src/model/physics/mathaven.ts) for them was initially generated by a combination of [Claude, Qwen and GPT-4o](./dist/diagrams/mathaven.md).
