a shopper walks west 35m west, another 17m west and then 67m east.

what is the resultant displacement?

see other post.

-15

To find the resultant displacement, we need to add up the individual displacements in the given directions.

First, let's assign positive (+) and negative (-) signs to indicate the direction of displacement. Let's assume west is the negative direction and east is the positive direction.

The first displacement is 35m west, so it would be -35m.
The second displacement is 17m west, so it would also be -17m.
The third displacement is 67m east, so it would be +67m.

Now, let's add up the displacements:

-35m + (-17m) + 67m

To simplify the calculation, we can rearrange the terms:

(-35m - 17m) + 67m

Now, let's perform the addition:

-52m + 67m = 15m

Therefore, the resultant displacement is 15m.
