Question

two balls collide. under which circumstances will they exert equal and opposite forces on each other? (1 point)
in all situations
if both are moving at the same speed when they collide
if they have the same mass
if the system is closed

Explanation:

According to Newton's third - law of motion, for every action, there is an equal and opposite reaction. This law applies to all interactions between objects, and two balls colliding are no exception. The forces they exert on each other are always equal and opposite regardless of their speeds, masses, or whether the system is open or closed.

Answer:

in all situations
