Question

one of these representations is not like the others. tap on the one that doesn’t belong.
the object’s acceleration is directed downward.
the object’s horizontal velocity is constant; it’s vertical velocity is changing.
arrows represent velocity vectors

Explanation:

Step1: Analyze the table

The table shows time ($t$) and components of velocity ($v_x$ and $v_y$). $v_x$ is constant at 16.0 m/s and $v_y$ changes with time following $v_y = v_{y0}-gt$ (where $g = 9.8m/s^2$), indicating a - 9.8 m/s² vertical acceleration.

Step2: Analyze the text statements

The statements "The object's acceleration is directed downward." and "The object's horizontal velocity is constant; it's vertical velocity is changing." are consistent with the data in the table.

Step3: Analyze the vector - diagram

The vector - diagram only shows vertical velocity vectors. It does not convey information about the constant horizontal velocity as clearly as the table and the text statements.

Answer:

The vector - diagram (the one with only vertical velocity vectors)
