Two straight lines drawn on the same dis...

Two straight lines drawn on the same displacement time graph make angles `30^(@)" and "60^(@)` with time axis respectively. Which line represents greater velocity? What is the ratio of the two velocities?

Text Solution

Verified by Experts

`v_(A)"/"v_(S)= tan 30^(@)"/"tan 60^(@)= 1"/"sqrt(3)"/"sqrt(3). 1"/"3`.
Because slope of the curve gives the velocity.
