the chart shows data for four different moving objects. which shows the order of the objects kinetic…

Answer:

W, Y, Z, X

Explanation:

Step1: Recall kinetic - energy formula

The formula for kinetic energy is $K = \frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity.

Step2: Calculate kinetic energy of object W

$K_W=\frac{1}{2}\times10\times8^{2}=\frac{1}{2}\times10\times64 = 320$ J.

Step3: Calculate kinetic energy of object X

$K_X=\frac{1}{2}\times18\times3^{2}=\frac{1}{2}\times18\times9 = 81$ J.

Step4: Calculate kinetic energy of object Y

$K_Y=\frac{1}{2}\times14\times6^{2}=\frac{1}{2}\times14\times36 = 252$ J.

Step5: Calculate kinetic energy of object Z

$K_Z=\frac{1}{2}\times30\times4^{2}=\frac{1}{2}\times30\times16 = 240$ J.

Step6: Order kinetic energies

Comparing the values: $K_X = 81$ J, $K_Z = 240$ J, $K_Y = 252$ J, $K_W = 320$ J. The order from least to greatest is X, Z, Y, W.
