Answer:
The average force applied to the baseball is 8.25kN
Step-by-step explanation:
This problem bothers on the impulse of a force 
We know that the change in momentum is expressed as
Ft= mv-mu
Given 
Ft=16.5 kg-ms
Time t of impact =0.00200s
The force applied can be solved for 
By making F subject of formula
F= (mv-mu)/t
F=16.5/0.002
F= 8250N
F= 8.25kN
 
        
             
        
        
        
The answer would be C. This is because the larger the negative numbers get, the less value they have, so -8 would have a greater value than -9.
 
        
        
        
<h3>Answer: Choice C</h3>
======================================================
Explanation:
The x coordinate of the preimage point Q is x = 6.
The x coordinate of the image point Q' is x = 21.
The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2
You'll get this same value if you do the same steps with the y coordinates.
Therefore, the scale factor is 7/2 and the dilation rule is 
Note: 7/2 = 3.5
