Question

The displacement S and time T graph for two moving objects A and B are straight line in client at 30 degree with the time axis and 30 degree with the displacement Axis respectively then what would be their velocities ratioVa/Vb?

Answer 1

Answer:

1/3

Explanation:

Velocity=Slope of S-T graph=tan(theta)

where, theta is angleade with X-axis that is time axis

$va = \tan(30) = \frac{1}{ \sqrt{3} } \\ vb = \tan(60) = \sqrt{3 } \\ \frac{va}{vb} = \frac{1}{3}$
