A line connecting the points (-3,0) and (x, -6)has slope -1. Determine x.
ankoles [38]

Answer:

x=3

Step-by-step explanation:

We can use the slope formula to help complete this question

m = (y2-y1)/(x2-x1)

-1 = ( -6-0)/(x- -3)

-1 = -6/ (x+3)

Multiply each side by (x+3)

-x-3 = -6

Add 3 to each side

-x -3+3 = -6+3

-x =-3

Multiply each side by -1

x = 3

suter [353]

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 m/s^2 when the board hits the victim

To find: Force exerted on victim

<em><u>The force is given by formula:</u></em>

F = mass \times acceleration

From given,

mass = 2 \text{ kg }\\\\Acceleration = 10 m/s^2

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

Force = 2 \times 10 = 20

Thus force exerted on victim is 20 newton
