Question

A person travels from A to B through point C as shown in figure. Find the distance and displacement?

Answer 1

Answer:

distance = 80+60

=140m

displacement =AB

AB²=AC²+BC²(by pythagoras th. )

AB²=80²+60²

AB²=6400+3600

AB²=10000

AB=100

Answer 2

Answer:

Distance = 140 m and displacement= 100m.

Step-by-step explanation:

Given: A person travels from A to B through point C.

To find the distance and displacement.

We know that, Distance is the actual path length traveled by an object in the given interval of time during the motion.

And displacement is the difference between the final and initial positions of the object in a given interval of time.

By the figure & using definition we can see that :

Distance = 80m +60m

               = 140m.

And displacement is given by the side AB.

Which can be found by using Pythagoras theorem i.e;

(Hypotenuse)^2= (perpendicular)^2+(base)^2

(AB)^2 = (80)^2+(60)^2

           =6400+3600

(AB)^2=10000

       AB=100m

So, the distance = 140 m and displacement= 100m.
