Bella walks 4 m north,13 m east and 4 m south.what distance did she travel? and what is her displacement?

a. d = 4 + 13 + 4 =

b. Disp. = 4i + 13 - 4i = 13 + 0i = 13 m.

Explain and give the calculation on how to calculate the question above

To determine the distance Bella traveled, we need to calculate the total length of her path. The distance is the sum of the individual distances she traveled in each direction. In this case, Bella walked 4 meters north, 13 meters east, and 4 meters south.

To find the distance traveled north and south, we can subtract the southward distance from the northward distance, which gives us 4 - 4 = 0 meters.

For the eastward direction, there is no counteracting distance traveled, so the distance remained at 13 meters.

Therefore, the total distance Bella traveled is 0 + 13 = 13 meters.

Now let's determine Bella's displacement. Displacement refers to the straight-line distance from the starting point to the ending point. In this case, Bella walked north and then returned south. Therefore, her displacement can be calculated by subtracting the southward distance from the northward distance.

Bella traveled 4 meters north and 4 meters south, resulting in a net displacement of 4 - 4 = 0 meters.

So, Bella's displacement is 0 meters, meaning she ended up at the same position from where she started.
