What’s the answer ??????

According to Newton's second law of motion: "The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the object's mass" .

Because the vehicle travels at a constant speed, its acceleration at zero, so

$A=F_{net}/m$ ,

$F_{net}=A*m; A=0\\F_{net}=0$

HELP PLEASE IT EASY! + no files please!!

NARA [144]

Answer:

GIVEN :-

Ordered pairs given are :-

(2 , -1)
(-5 , 3)
(4 , 3)
(-2 , -3.5)
(0.5 , 1.75)

TO FIND :-

Correct quadrant for each ordered pair.

FACTS TO KNOW BEFORE SOLVING :-

While writing the co-ordinates of a point , its ordered pair is always in the form of ( x , y ) where x = x-coordinate of the point & y = y-coordinate of the point.

In Quadrant 1 , the coordinates of a point is always = ( +x , +y ) because Quadrant 1 lies between the positive side of x-axis & positive side of y-axis.
In Quadrant 2 , the coordinates of a point is always = ( -x , +y ) because Quadrant 2 lies between the negative side of x-axis & positive side of y-axis.
In Quadrant 3 , the coordinates of a point is always = ( -x , -y ) because Quadrant 3 lies between the negative side of x-axis & negative side of y-axis.
In Quadrant 4 , the coordinates of a points is always = ( +x , -y ) because Quadrant 4 lies between the positive side of x-axis & negative side of y-axis.

SOLUTION :-

(2 , -1) is in Quadrant 4 because it's x-coordinate is positive whereas its y-coordinate is negative.
(-5 , 3) is in Quadrant 2 because its x-coordinate is negative but y-coordinate is positive.
(4 , 3) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.
(-2 , -3.5) is in Quadrant 3 because both its x-coordinates & y-coordinates are negative.
(0.5 , 1.75) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.
