Cat walks 100 m  East, then turns around and walks 25 m west. What is the cats displacement? a) 75 m

b) 100 m

c) 25 m

d) 125 m

Explanation:

If a cat walk 100m East, this means that it is walking in the positive x direction, the distance will therefore be +100m

If it turns around and walks 25 m west, the direction of movement is in the negative x direction i.e -25m

Taking the sum;

Displacement = +100m - 25m

Displacement of the cat = 75m

hence the cats displacement is 75m

i think they are all correct

explanation:

they seem good

find the sum of the two horizontal vectors and the sum of the two vertical vectors
