Two people of unequal mass are initially standing still on ice with negligible f

Question

Two people of unequal mass are initially standing still on ice with negligible friction. They then simultaneously push each other horizontally. Afterward, which of the following is true?
The kinetic energies of the two people are equal.

The speeds of the two people are equal.

The momenta of the two people are of equal magnitude.

The center of mass of the two person system moves in the direction of the less massive person.

The less massive person has a smaller initial acceleration than the more massive person.

Explanation / Answer

The answer is the last option. i.e. The less massive person has a smaller initial aceleration than the more massive persion. This is because, a = F/m Acceleration is inversely proportional to the mass of the person.
