Question

The position-time graphs of two cars A and B are straight lines making angles 30" and 60" with the time axis
respectively. The ratio of velocities of A and B is
​

Answer 1

the ratio of velocities of A and B is 1/3

Explanation:

now we know if x-t graph is given then the slope implies the velocity . so here .........

velocity of A

______________

velocity of B

= 1/√3 ÷ √3

=. 1/3
