Question

9 hot spot 10 points consider a basket ball passed from one player to another in a long ark. which of the following graphs could represent the horizontal acceleration (a_x)?

Explanation:

Step1: Analyze horizontal motion

In the absence of air - resistance, the horizontal motion of a projectile (like a basketball in this case) is a uniform - motion. The acceleration in the horizontal direction $a_x$ is zero because there is no horizontal force acting on the ball (assuming no air - resistance).

Step2: Identify the graph

The graph that represents a horizontal acceleration of zero is a horizontal line at $a_x = 0$ on the $a_x$ - $t$ graph.

Answer:

The graph that is a horizontal line at $a_x = 0$ (the third graph from the left in the top - row among the given graphs).
