Answer:
The quantities that always have equal magnitude for both masses during the collision are change in momentum of the colliding bodies and force exerted by each body
Explanation:
During collision of two bodies, the following quantities are affected;
Kinetic energy of the colliding bodies
change in momentum of the colliding bodies
Force exerted by each body
Two bodies that stick together after collision is inelastic collision.
For inelastic collision, the kinetic energy before collision is greater than kinetic energy after collision.
Change in momentum is zero, that is, momentum before collision is equal to momentum after collision.
According Newton's third law of motion, the force exerted by each body is equal but acts in opposite direction.
Therefore, the quantities that always have equal magnitude for both masses during the collision are change in momentum of the colliding bodies and force exerted by each body
