Question

the velocity time graph show two straight line A and B. a is inclined at an angle of 30degree at t axis and b is inclined at 30 degree on v axis what is the ratio of acceleration of A and B?

Answer 1

The slope of v-t graph gives us the acceleration, so a is inclined at 30 degrees, hence tan 30 = 1/root(3) 

b is inclined at 60 degrees wrt t axis, slope is tan 60 degrees = root (3) 
 Ratio A:B = 1:3 

Answer 2

1:3 May this answer help you
