Question

newtons third law quick check
two metal balls with the same mass hang so that they are touching each other. the ball on the
left is pulled to the side and released. what will happen when it swings back and hits the ball on
the right? (1 point)
the ball on the right will swing to the right.
both balls will swing to the right.
both balls will swing to the left.
the ball on the left will stop, and the ball on the right will remain still.

Explanation:

When the left ball hits the right ball, according to Newton's third law (action - reaction) and conservation of momentum (since the masses are equal), the left ball transfers its momentum to the right ball. The left ball stops (loses its momentum) and the right ball gains that momentum and swings to the right.

Answer:

The ball on the right will swing to the right.
