Question

A person walking on a straight line for 60m.
Then he turn right 90 degree and travel 100m.
Again he turn right 90 degree and travels 60m.
1) Draw the path of the person?
2) Find the total distance travelled ?
3) Find the total displacements?​

Answer 1

Answer:

hope you have got your answer.

Answer 2

Given:

A person walking on a straight line for 60m. Then he turn right 90 degree and travel 100m. Again he turn right 90 degree and travels 60m.

To find:

• Total distance travelled.

• Total displacement.

Diagram:

$\boxed{\setlength{\unitlength}{1cm}\begin{picture}(6,6)\put(2,2){\vector(0,1){1.5}}\put(2,3.5){\vector(1, 0){2}}\put(4,3.5){\vector(0,-1){1.5}}\put(1,3){60m}\put(3,4){100m}\put(4.5,3){60m}\put(2,2){\circle*{0.2}}\end{picture}}$

Calculation:

Distance is defined as the total path length travelled by the object.

$\boxed{distance = 60 + 100 + 60 = 220 \: m}$

Displacement is the shortest line between the starting and stopping point of the object.

$\boxed{displacement = 100 \: m}$

Other important things to know:

• Distance is always positive , but displacement can be positive, negative or zero.

• Distance is a vector ,but Displacement is a vector.
