Final answer:
The transition sequence for trunk action in sidearm striking from block rotation to differentiated rotation is true. Regarding the displacement question, the answer is false because both individuals have the same displacement.
Step-by-step explanation:
The statement that the developmental transition for trunk action in sidearm striking is first block rotation and then differentiated rotation is True. Block rotation refers to moving the trunk as a single unit, without much rotation at the waist, a stage often seen in beginners. Differentiated rotation, on the other hand, involves a more advanced skill where the upper trunk rotates separately from the lower trunk, allowing for more power and better control during sidearm striking tasks, as commonly seen in sports or physical activities.
In relation to the True or False question provided, displacement is a vector quantity that depends only on the initial and final position of a person's path. Therefore, regardless of their respective paths, if both persons end up at the same final position, their displacements are the same. The answer to this question would be False as both individuals' displacement would be identical, being a diagonal line from the starting point to the upper right, following the path of 2 blocks east and 5 blocks north.
