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
No the square root of 16 is 4 which is a whole number therefore it is rational not irrational
Hello, I’m not super sure about the last part but to get 1 divide 20 by 20 and then from 1 multiply by 12 to get 12. I hope this helps :)
Answer: c = 8 yards
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(45) = c/(8*sqrt(2))
c = 8*sqrt(2)*cos(45)
c = 8*sqrt(2)*(1/sqrt(2))
c = 8
----------------
Optionally, you can use the 45-45-90 triangle template which says that the length of the leg of this triangle is x and the hypotenuse is x*sqrt(2)
Since 8*sqrt(2) is the given hypotenuse, this must mean x*sqrt(2) = 8*sqrt(2) so x = 8
