Question

one of these representations is not like the others. tap on the one that doesnt belong.
\the objects horizontal velocity is constant; its vertical velocity is changing.\

t (s)	vx (m/s)	vy (m/s)
1.0	0.0	-9.8
2.0	0.0	-9.8
3.0	0.0	-9.8
4.0	0.0	-9.8

Explanation:

Step1: Analyze the first two diagrams

They show velocity - vector representations of an object in motion. The horizontal and vertical components of velocity are depicted with arrows.

Step2: Analyze the table

The table shows values of time ($t$), horizontal velocity ($v_x$) and vertical velocity ($v_y$). However, the given values of $v_x = 0$ and $v_y=- 9.8$ m/s for all time - steps are incorrect for a typical projectile motion scenario. In projectile motion, the horizontal velocity is constant (non - zero in most cases when there is an initial horizontal component) and the vertical velocity changes due to gravity. Here, the table implies no horizontal motion and a constant vertical velocity which is wrong.

Answer:

The table is the one that doesn't belong.
