## A particle of mass 'm' strikes a wedge of mass 'M' horizontally as shown in the figure. STATEMENT-1 : If the collision is perfectly inelastic then, it can be concluded that the particle sticks to the wedge. STATEMENT-2 : In perfectly inelastic collision velocity of both bodies is same along common normal just after the collision.

A
Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
B
Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1.
C
Statement-1 is True, Statement-2 is False.
