Eight cars move along smooth horizontal roadways in the same direction at specified speeds, v, toward identical barriers. All the cars have the same size and shape, but carry different loads and, hence, have different masses, m. The cars collide with the barriers and come to a stop after having traveled some distance. Assume the force exerted on each of the cars by their respective barrier is the same. Rank the situations described here from greatest to smallest according to the stopping distance of each vehicle. If any situations yield the same stopping distance, give them the same ranking. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.) a. m = 1,800 kg; v = 20 m/s b. m = 1,800 kg; v = 40 m/s c. m = 1,800 kg; v = 60 m/s d. m = 5,400 kg; v = 20 m/s e. m = 3,600 kg; v = 20 m/s
I do not understand how to do this question:
The answer is G>H>C>F>B>D>E>A but I do not understand why that is the correct answer. Could you explain the formulas used for solving this?

a. m = 1,800 kg; v = 20 m/s
b. m = 1,800 kg; v = 40 m/s
c. m = 1,800 kg; v = 60 m/s
d. m = 5,400 kg; v = 20 m/s
e. m = 3,600 kg; v = 20 m/s
f. m = 3,600 kg; v = 40 m/s
g. m = 3,600 kg; v = 60 m/s
h. m = 5,400 kg; v = 40 m/s
