So your answer would be : B
        
             
        
        
        
So your finding acceleration first which is 30m/s divides by 6 seconds equals 5m/s^s and then multiply that by 1,400 kg and you have net force which is 7,000N
        
             
        
        
        
The answer is this, but i don't know how to simplify it. 3x^100000000<span />
