Question

The displacement time graph of two bodies a and b makes an angle 45 degree and 30 degree the time axis what is the ratio of their velocities

Answer 1

For uniform velocities (straight line D-T plots), the velocity is simply the tangent of the angle made with the positive X-axis.

So the ratio of velocities is simply tan30∘tan45∘tan⁡30∘tan⁡45∘

=13–√=13
