the chart shows data for an object moving at a constant acceleration. which values best complete the chart…

Explanation:

Step1: Recall acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time. Given the object has a constant acceleration and at $t = 0$, $u=0$. Let the acceleration be $a$.

Step2: Find velocity at $t = 1$

Using $v=u + at$, with $u = 0$, $t = 1$ and assuming acceleration $a = 2\ m/s^{2}$ (we can find this by checking the options). Then $v=0+2\times1 = 2\ m/s$, so $X = 2$.

Step3: Find velocity at $t = 2$

Using $v=u+at$, with $u = 0$, $t = 2$ and $a = 2\ m/s^{2}$, then $v=0 + 2\times2=4\ m/s$, so $Y = 4$.

Step4: Find velocity at $t = 3$

Using $v=u+at$, with $u = 0$, $t = 3$ and $a = 2\ m/s^{2}$, then $v=0+2\times3 = 6\ m/s$, so $Z = 6$.

Answer:

X: 2 Y: 4 Z: 6
