Answer:

Hello! The answer is D or X, Z, Y, W

Explanation:

Well to work out kinetic energy, you need to use the formula:

(1/2 * mass) * velocity^2 = Kinetic Energy (Joules)

W = (1/2 * 10) * 8m/s^2 = 320 J

X = (1/2 * 18) * 3m/s^2 = 81 J

Y = (1/2 * 14) * 6m/s^2 = 252 J

Z = (1/2 * 30) * 4m/s^2 = 240 J

If you put those in order, you get X, Z, Y, W, which is option D.

Answer:

D) X,Z,Y,W
