A firework moves upwards and then explodes into three fragments. The first fragment moves vertically with a speed of 50 m/s. The second moves at an angle of 100◦ from the vertical with a velocity of 20 m/s. The third moves at an angle of 120◦ from the vertical with a velocity of 23 m/s. All three pieces have a mass of 0.4 kg. (A) What is the horizontal component of the total momentum of the three fragments. (B) What is the vertical component of the total momentum of the three fragments. (C) Assume that no mass is lost during the collision. What is the initial velocity of the firework?
