The force exerted on victim is 20 newton
<em><u>Solution:</u></em>
An attacker swings a board with a mass of 2 kg toward a victim
The acceleration is 10
when the board hits the victim
To find: Force exerted on victim
<em><u>The force is given by formula:</u></em>

From given,

<em><u>Substituting the values in formula,</u></em>

Thus force exerted on victim is 20 newton
Answer:
width = let width be w
area = 140
length = 2w-6
Area of a rectangle = l*b
⇒ 2w-6*w=140
⇒ 
SAS but i’m not sure. i’m doing this right not but each triangle shows two sides and angle so i would pick SAS
A because if you use T3 it wouldn’t have make sense so only reasonable and solution that works is A
