Question

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) Responses The ball on the left will stop, and the ball on the right will remain still. The ball on the left will stop, and the ball on the right will remain still. Both balls will swing to the left. Both balls will swing to the left. The ball on the right will swing to the right. The ball on the right will swing to the right. Both balls will swing to the right.

Answer 1

When the left ball is pulled to the side and released, it will swing down due to gravity and collide with the right ball. Since both balls have the same mass and are initially at rest, this situation resembles an elastic collision.

In an elastic collision between two objects with the same mass, if one object is initially moving and the other is stationary, the moving object will come to a stop after the collision, and the stationary object will move away with the same speed as the first object.

Therefore, when the left ball collides with the right ball, the left ball will stop, and the right ball will swing to the right.

So the correct response is: **The ball on the right will swing to the right.**
