A billiard ball travels 23 cm in the positive direction , hits the cushion and rebounds in the negative direction , and Finally comes to rest 8.0 cm behind its orbital position.

What’s the displacement of the ball?

Respuesta :

Explanation :

Displacement refers to the distance between the final and the initial position. Hence the displacement of the ball will be the difference between the initial and the final displacement.

Let the initial position be 0.

Final position = 8 cm

So the difference between initial position and final position = 0 – 8 = - 8 cm.

So the billiard ball comes to rest 8.0 cm behind its orbital position.
