Acontainer explodes and breaks into three fragments that fly off 120° apart from each other, with mass ratios 1: 4: 2. if the first piece flies off with a speed of 6.0 m/s, and the 3rd piece flies off at 3.0 m/s what is the speed of the second fragments? (all fragments are in the plane.)

V₂ = 1.5 m/s

Explanation:

given,

speed of the first piece = 6 m/s

speed of the third piece = 3 m/s

speed of the second fragment = ?

mass ratios = 1 : 4 : 2

fragment break  fly off = 120°

α = β = γ  = 120°

sin α = sin β = sin γ = 0.866

using lammi's theorem

A,B and C is momentum of the fragments

4 x V₂ = 2 x 3

V₂ = 1.5 m/s

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the inner core.

good luck: )
