Question

A soccer ball is traveling downfield with a force of 1.2 kN and strikes another soccer ball that is stationary. Which of the following describes the result of the collision?(1 point)
Responses

Neither ball will move after impact.
Neither ball will move after impact.

The stationary soccer ball will begin moving upfield and the ball that struck it will slow down.
The stationary soccer ball will begin moving upfield and the ball that struck it will slow down.

The stationary soccer ball will begin moving downfield and the ball that struck it will accelerate.
The stationary soccer ball will begin moving downfield and the ball that struck it will accelerate.

The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.

Answer 1

To analyze the collision between the moving soccer ball (with a force of 1.2 kN) and the stationary ball, we can apply the principles of momentum conservation and the nature of elastic collisions.

In this case:

1. The moving soccer ball has momentum due to its motion.
2. The stationary ball has no initial momentum, as it is not moving.

When the moving soccer ball strikes the stationary ball, it will transfer some of its momentum to the stationary ball. The stationary ball will begin to move in the direction the initial ball was traveling (downfield). Meanwhile, the moving ball will experience a change in velocity due to the collision, which will slow it down.

Thus, the accurate response is:

**The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.**
