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.
