Two bodies of masses m and 4 m are moving with equal K.E.

Two bodies of masses m and 4 m are moving with equal K.E. The ratio of their linear momenta is

m₁ = m, m₂ = 4 m
K . E₁ = K . E₂

	1	m₁v₁² =	1	m₂v₂² ;	1	mv₁² =	1	mv₂²
	2		2		2		2

	v₁	= 2 ⇒ v₁ = 2v₂
	v₂

	Linear momentum of first body
	Linear momentum of second body

=	m₁v₁	=	m .2v₂	=	1
