Answer:
The answer is -0.5m/s2
Explanation:
I did the test and got it right.
 
        
             
        
        
        
The momentum of an object is equivalent to the product of the object's mass and velocity. Computing the momentum for each ball:
A- 15 * 0.7 = 10.5
B- 5.5 * 1.2 = 6.6
C- 5.0 * 2.5 = 12.5
D- 1.5 * 5.0 = 7.5
Therefore, ball C has the greatest momentum.
        
                    
             
        
        
        
Great question the answer is -25x.
