Question

the ratio of velocities represented by lines A and B in the graph below is
​

Answer 1

Answer:

3

Explanation:

the solution is given in attachment given above

Answer 2

Answer:

3:1

Explanation:

the slope of the displacement time graph gives the velocity

slope= tan(theta)

here you've two angles , i.e. 60 and 30

therefore

slopeA/ slopeB gives the ratio of velocities.

tan60/tan30 = 3

hence is the ratio .

hope this helped .
