the problem:

1. a 2 kg firework is shot vertically, at v=50 m/s

a. what is the velocity and momentum of the firework as it reaches a height of 50 m'?

b. in the height of 50 m' the firework explodes into two equal particles. particle 1 moves horizontally in 30 m/s.

what's the horizontal velocity of particle 2 after the explosion? what's the velocity of particle 2 and it's direction.

c. what's the kinetic energy of particle 2 when it reaches the floor?

this is my answer, explaining all the steps i took:
