Question

Question number 3 is the one I need help on

Answer 1

Given,

Distance Sandy covered while walking east, s₁=10 blocks.

Distance Sandy covered while walking west, s₂=5 blocks.

The total distance covered is the sum of the two distances given in the question.

That is,

`\begin{gathered} \text{distance}=s_1+s_2 \\ =10+5 \\ 15\text{ blocks} \end{gathered}`

The displacement is the shortest distance between the starting and ending point of a path.

Let us assume that the eastward direction is positive and the westward direction is negative.

Thus the total displacement of Sandy is given by,

`\text{displacement}=s_1-s_2`

On substituting the known values,

`\text{displacement}=10\text{-5=5 blocks.}`

Therefore total distance covered by Sandy = 15 blocks.

And the total displacement of the Sandy = 5 blocks
