Assertion (Ꭺ)
A particle of mass m strikes a wedge of mass M horizontally as shown in the figure. If collision is perfectly inelastic then, it can be concluded that the particle sticks to the wedge.
Particle of Mass M Strikes a Wedge of Mass M Horizontally
In above we figure we show that the triangle, and the particle have mass m and M.
Reason (Ꭱ)
In perfectly inelastic collision velocity of both bodies is same along common normal just after collision.
