- 2. A projectile fired vertically upwards exploded into two fragments at the top of the trajectory. The velocity,of the first fragment weighing 0.5 kg immediately after the rupture is directed horizon- tally and is equal to 800m/s. The mass of the second fragment is 2 kg . Accept that the resistance of the spirit can be ignored. a) What is the momentum of the first fragment immediately after the rupture? b) What is the velocity of the second fragment immediately after the rupture? c) Which fragment will fall to the ground first?Justify your answer.
