013 The displacement (x) Verses time t for bodies (1) and (2) is
shown in fig
(as what can you say about type of motion
represented by the bodies and in what
(b) What is the ratio of their velocities.
direction​

Answer 1

Answer:

_____________________________

• velocity is the slope of displacement-time graph
• slope of 1st body

=tanx

=tan45

=1

• slope of 2nd body

=tanx

=tan(90-30)

=tan60

=√3

_____________________________

a) both bodies are moving with uniform velocities.(because, their slope is constant(1&√3))

and they are moving in opposite direction (clear from the graph)

_____________________________

b)Ratio of velocities=Ration of slopes

i.e,

$\frac{v1}{v2} = \frac{1}{ \sqrt{3} }$
