But calculating the distances with nonstandard angles like 10 degrees etc. After the fifth collision, the ball starts moving away from the apex of the cone. It seems like a mechanics problem and I tried it by calculating the angle at which the ball collides with the cone. Find the number of collisions of the ball with the cone and the distance of the closest approach of the ball from the apex.

All the collisions of the ball with the cone are perfectly elastic. The distance of point P from the apex O is x = 10 cm and the apex angle of the cone is β = 20°. In free space, a particle is projected from a point P on-axis of a fixed rigid cone AOB, at an angle α = 37° with the axis (see figure). I came across a problem which is as follows: Nil Asks: Analogy between reflected rays and elastic collisions of an object
