The chart shows data for four different moving objects.

A 3 column table with 4 rows. The first column is labeled object with entries W, X, Y, Z. The second column is labeled mass in kilograms with entries 10, 18, 14 and 30. The last column is labeled velocity in meters per second with entries 8, 3, 6, 4.

Which shows the order of the objects’ kinetic energies, from least to greatest?

W, Y, X, Z
Z, X, Y, W
W, Y, Z, X
X, Z, Y, W

Kinetic energy: KE = 1/2 m v^2.

Calculate each:
- W: 0.5(10)(8^2) = 320 J
- X: 0.5(18)(3^2) = 81 J
- Y: 0.5(14)(6^2) = 252 J
- Z: 0.5(30)(4^2) = 240 J

Order least to greatest: X (81), Z (240), Y (252), W (320). So: X, Z, Y, W.
