Question

5. Suppose a ball of mass 'm' is thrown vertically upwards with an initial speed 'v', its speed
decrease continuously till it becomes zero. Therefore, the ball begins to fall downward
and attains the speed 'y' again before striking the ground. It implies that the magnitude of
initial and final momenta of the ball are same. Yet, it is not an example of conservation of
momentum. Explain why.​
