.1. Suppose a ball of mass m is thrown vertically upward with an initial speed v. Its speed decreases
continuously till it becomes zero. Thereafter, the ball begins to fall downward and attains th
speed v again before striking the ground. It implies that the magnitudes of initial and final
momentums of the ball are same. Yet, it is not the examples of conservation of momentum.
Explain why?
