Question

The chart shows data for four different moving objects.

Which shows the order of the objects' kinetic energies, from
least to greatest?
Object
Velocity (m/s)
w
Mass (kg)
10
18
14
30
W, Y, X, Z
Z, X, Y, W
W, Y, Z, X
X. Z. Y. W
30

Answer 1

X, Z, Y, W

I just took the quiz

Answer 2

Step-by-step explanation:

The formula for KE is KE = 1/2 m v^2

If they are all traveling at the same v (m/s) then the order of KE will be dependent on their masses.

10 < 14 < 18 < 30

30 has the most KE (see the formula) and 10 has the least KE

I've given you the answer. You will have to sort out WXYZ
