mass of a body = 1 kg
mass of another body= 5 kg.
let the velocity of 1 kg massed body be= V'
again, the velocity of 5 kg massed body be= V"
than , kinetic energy= 1/2 mv^2.
--->given,
kinetic energy of the both bodies are
same.
than ,
1/2mv'^2= 1/2 mv"^2.
hence, v'/v"= 5/1
than, v'/v"=√5:1 (answer).
