Final answer:
The Ladybug's total displacement is calculated based on its movements along the measuring stick, with positive displacement toward the wall and negative displacement toward the floor. The final displacement is 32 cm toward the wall, putting the ladybug at the 68 cm mark starting from the initial 100-cm position.
Step-by-step explanation:
The question provided appears to describe various scenarios involving a ladybug's movement and its displacement which are problems typically encountered in a Physics course. The main focus of the question seems to be understanding vectors and displacement, which is a fundamental topic in kinematics, a branch of classical mechanics that is integral to high school Physics.
Based on the information given, we can determine the ladybug's displacement as it moves along the measuring stick by analyzing the description of its movements. The ladybug's movements are detailed as follows: from its initial 100-cm mark, it moves 15 cm toward the floor, then 56 cm toward the wall, then another 3 cm toward the floor, followed by 25 cm toward the floor once more, and finally 19 cm toward the wall. By calculating the total displacement considering the direction towards the wall as positive and the direction towards the floor as negative, we find out that the total displacement is -15 cm + 56 cm - 3 cm - 25 cm + 19 cm, which simplifies to +32 cm toward the wall.
Therefore, the resultant displacement vector points away from the initial 100 cm mark, and after accounting for the total displacement, the final resting position of the ladybug on the stick is at the 68 cm mark, closer to the wall-end of the stick.
