This option suggests that the momenta of the two masses are the same. Momentum is the product of mass and velocity, so if the masses have the same velocity, their momenta will indeed be the same.
This option suggests that the momenta of the two masses can be different. However, if they have the same individual speeds, their momenta will be the same.
This option suggests that the kinetic energies of the two masses can be different. Kinetic energy depends on both mass and velocity, so if the masses have the same individual speeds, their kinetic energies will also be the same.
This option suggests that the total energies of the two masses are the same. This statement is true because the total energy includes both kinetic and potential energy, and the question does not mention potential energy.
The correct statement is A. Their momentums are same. If two equal masses are in motion with the same individual speeds, their momenta (momentum = mass x velocity) will be the same.
