SOLUTION —

The line which has greater slope has greater velocity.

Thus, the line which makes an angle of 60° with time axis has greater velocity.

Ratio of two velocities

= tan 30^o/tan 60^o

= 1/3

Two straight lines drawn on the same x-t curve make angles 30° and 60° with time axis. Which line represents greater velocity? What is the ratio of the two velocities?
