Answer:
KE = 6250 Joule.
Step-by-step explanation:
Every moving body has kinetic energy and it is given by the expression

where the moving body has m as the mass and v as the velocity.
If m is in Kg and v is in meter/sec, then KE will be expressed in Joule.
Now, in this case, m = 500 and v = 5 meter/sec.
So,
Joule. (Answer)
