Kinetic Energy 

KE=(mass) x (velocity )squared
                   divided by
                      2
unit=Joule 

example:
m=50kg
v=5m/s
KE=?
                    
solution:

KE= (50kg) (5m/s)²
           divided by
                2

KE=(50kg) (25m²/s²)
          divided by
               2
KE=(1250kg m²/s²
            divided by
               2
KE=625J

Ihope this will help you to understand your lesson......
