Question

a drone of mass 500g is flying from west to east with a speed of 25 m/s and electrical problem causes it to explode into three pieces one piece has a mass of 100g and it flies North at a speed of 3 m/s the second piece has a mass of 200 g and fly south with the speed unknown and the third piece has 200g and flies forward with a speed unknown we need to find the two unknown speeds so the speed of the second piece and a speed of the third piece

5. (20 points) A drone of mass 500g is flying from West to East with a speed of 25 0 m/ An electrical problem causes it to explode into 3 pieces. One piece, of mass m 100g, flies North at a speed 300 m/s. a second piere of mass m2 200g flies South with a speed and a third pie ma 200g, flies forward with a s Find and

Explanation / Answer

from momentum conservation

intial momentum pix = 0.5*25 = 12.5 kg m/s i

piy = 0

final momentum along x axis pfx = 0.2*v3i

along y axis pfy = 0.1*3j-0.2*v2j

piy = pfy

0.2v2 = 0.3

v2 = 3/2 = 1.5 m/s j

pix = pfx

12.5 = 0.2 v3

v3 = 62.5 m/s i
