The chart shows data for four different moving objects.

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

A.) W, Y, X, Z

B.) Z, X, Y, W

C.) W, Y, Z, X

D.) X, Z, Y, W

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.

thermal energy is the answer

we need to know the time interval during which the force acts. impulse of force = momentum change
