Answer:
I.D.K but the same measure they use to judge will be used to judge them
Explanation:
 
        
                    
             
        
        
        
Near Earth's surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.
        
             
        
        
        
Kinetic energy=1/2mv^2 
=1/2(142*10^-3)(42.9)^2=130.6=131J
