Question

The displacement time graph for two particles X and Y are straight lines making angles of 30"
and 60° with the time axis. What is the ratio of the velocities of Y and X?​

Answer 1

Explanation:

Slope of displacement-time graph gives the instantaneous velocity of the body.

Slope of particle A =tan30°

Slope of particle B =tan60°

So, ratio of velocity

VA uponVB=

tan30° upon tan60° =

1/ √3 upon √3=

1 upon 3
