Question

The position-time graphs of two cars A and B are straight lines making angles 30° and 60° with the time ay
respectively. The ratio of velocities of A and B is
(1) 1:13
(2) 1:3
(3) 3:1
(4) 3 : 1​

Answer 1

For position-time graph..the value of tan theta i calculated as the velocity of the graph...

so

tan 30°= 1/√3

tan 60°=√3

so.. 1/√3÷√3

= 1:3

so your answer will be option 2.
