GIven m1v1 = m2 v2 -----------------(1)
Needed m1v12 / m2v22 = v1 / v2
But right from (1) v1 / v2 = m2 / m1
Given m1 = 1 g and m2 = 4 g
So required ratio of KE = 4:1
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
This is called an elastic collision. In this case both momentum and kinetic energy is conserved.
Light is made up of particles (called photons). They have both kinetic energy and momentum.
Kinetic - how quickly something reacts.Thermodynamic - the energies required.

The Hamiltonian.
Temperature. Temperature is a measure of the average kinetic energy of particles of the substance.

Kinetic energy = K.E. = 1/2 (m)(v)2. Since mass, m, is part of this equation, we see that two particles of equal velocity but of different masses have different kinetic energies. In the case of equal velocities, the particle with the lesser mass will have the lower kinetic energy. Remember that momentum is the derivative of K.E., and so the momentum of an object is also related to the mass of an object as well.
Thermal energy is the sum of kinetic energies, while temperature is the average of these kinetic energies.
