Momentum,P is same for both objects.Let the lighter object be
1Let the heavier object be
2.RATIO OF THEIR KINETIC ENERGY:= K.E 1/K.E 2= P²/2m1 ÷ P²/2m2P², P² get canceled.= 1/2m1÷1/2m2= 2m2/2m12,2 get cancelled.= m2/m1=mass of heavier object/mass of a lighter object can conclude that the heavy object has more K.EPROOF
: K.E = mv²/2K.E is directly proportional to the mass.The heavy object has more mass.So, it has more kinetic energy.
