What is the correct displacement for the following vectors : 4 km south ,2km north , 5 km south , and 5 km north

Let the four directions are along X and Y axis

North = +Y aixs

South = - Y axis

East = + X axis

West = - X axis

So displacements are given as

South

North

South

North

Now total displacement towards north is 5km + 2 km = 7 km

Now total displacement towards south is 5km + 4 km = 9 km

Now the net displacement of whole journey will be

d = 9 - 7 = 2 km towards SOUTH

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
