Question

An object moves from A to D through B and C along a rectangular path as shown in the figure. Find:
(A) the distance covered by the object.
(B) the displacement of the object.

Answer 1

Given Data:

Length of AB,$=15km$

Length of BC,$=9km$

Step 1: Distance covered:

Distance = Length of path travelled
Distance=length of AB+length of BC + length of CD
$D=15+9+15=39km$
Step 2: Displacement covered:
Displacement =Shortest path from initial to final position
d=length of AD

d=9km
