Give your conclusion !!​

Answer 1

$\huge\underline{\underline{\mathfrak\red{Answer}}}$

When a rigid body lie on a smooth horizontal surface and a particle is collided in the plane of the surface :-

★ Conservation of linear Momentum is applicable.

★ Conservation of angular momentum is applicable about any point but it is convenient to apply about centre of mass (COM).

Answer 2

Explanation:

when a rigid body lie on a smooth horizontal surface and a particle is collided in the plane of the surface then it will lead to conservation of angular and linear momentum.
