please tell th answer fastsuppose A ball of mass M is thrown vertically upward with initial speed be its speed is continuously until it's become zero therefore the Ball begins to fall downward net in the speed of the again before striking the ground it implies that the magnitude of the initial and final moment of the ball is same but still it is not example of conservation of momentum .explain why ?
