Question

Which of the following situations represents a negative displacement? (Assume positive position is measured vertically upward along a y-axis.) a. A cat stands on a tree limb. b. A cat jumps from the ground onto a tree limb. c. A cat jumps from a lower tree limb to a higher one. d. A cat jumps from a tree limb to the ground. Please select the best answer from the choices provided A B C D

Answer 1

Option-(D): "A cat jumps from a tree limb to the ground."

Step-by-step explanation:

Negative displacement(Assume positive position is measured vertically upward along a y-axis):

The displacement can be visualized going from the initial point been supposed as the ground level. While, the limb is considered more elevated as compared to the ground level. So, going from the lower level to the higher position is considered as positive displacement while the movement from the higher position to the lower point is considered as negative displacement.

Answer 2

A is wrong. There is no displacement. She's just sitting there.

C and B are both going up.

D is going down <<<==== answer.
