where
m is the mass of the student
v is the speed of the student
Let's use the formula above to calculate the kinetic energy of each student:
- Autumn: 
- Mohammed: 
- Lexy: 
- Chiang: 
Therefore, by looking at the numbers, we see that the correct answer is
Mohammed has less kinetic energy than Autumn
