hello. i tried to solve for the problem, which was quite difficult for me and i'm not sure whether i approached it correctly, so if someone will help me figure it out thank you!
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:
