Question

On a displacement -time graph ,two straight line make angle 30 and 60 with the Time axis . The rato of the velocities represented by them

Answer 1

Velocity = =Speed = slope of displacement time graph.

Therefore,

$v_1/v_2 = tan 30/tan 60 = 1/3$

Therefore ratio of the velocities represented by them are (1/3).

Answer 2

Answer:

V1/V2=1:3

Explanation:

In displacement-time graph we find velocity by taking tanzent of given angle

For 30degree, V1 =tan 30

For 60degree, V2=tan 60

v1/v2= tan 30 / tan 60= 1/3

v1 / v2= 1:3
