Final answer:
To find the ball's resultant displacement after hitting the wall, use the Pythagorean theorem with the initial distance and additional rolled distance.
Explanation:
The ball's resultant displacement can be calculated using the Pythagorean theorem.
To find the resultant displacement, you would add the initial distance of 10m from the wall to the additional distance of 2.5m that the ball rolls along the ground.
Using the Pythagorean theorem: Resultant displacement = √(10^2 + 2.5^2) = √(100 + 6.25) = √106.25 ≈ 10.31m.
