The answer would be:
6,250 joules
Here's how to do it:

KE = kinetic energy (joules)
m = mass (kg)
v = velocity (m/s)
So with that formula let's figure out what was given to you.
500 kg and 5m/s
You know which is which based on the unit.
m = 500kg
v = 5m/s

The unit
also means joules
So the final answer is 6,250 joules.
