Question

What is the physical interpretation of the x acceleration of the tennis ball? Would it be like "small x deceleration due to air resistance"? I'm not sure.

Explanation / Answer

From the graphs Y acceleration is clear and equal to slope of Y velocity time graph.

X velocity time graph is distributed at random.

In X direction velocity is uniform in the absence of air resistance. Then graph should be a straight line parallel to X axis.

Due to air resistance the acceleration arises along X axis which is proportional to velocity.

As X velocity vs time graph is distributed at random, air resistance also different for different times.
