Question

7. A body at rest is made to fall from the top of a tower.
Its displacement at different instants is given in the
following table :
Time (in s)
0-2 0-3
Displacement (in m) 0.05 0.20 0.45 0.80 1.25 1-80
Draw a displacement-time graph and state whether
the motion is uniform or non-uniform ?
0.1
0.4
0.5 0.6


This is a question from class 9.ICSE board physics book.

Answer 2

Given : A body at rest is made to fall from the top of a tower.  

displacement at different ins tants

Time (in s) 0.1 0.2 0.3 0.4 0.5 0.6  

Displacement (in m) 0.05 0.20 0.45 0.80 1.25 1.80

To Find :  Draw a displacement-time graph

Solution:

Time (in s)  Displacement (in m)

0.1                   0.05

0.2                  0.20

0.3                  0.45

0.4                  0.80

0.5                  1.25

0.6                   1.80

As Displacement time graph is non linear hence motion is non uniform
