Question

the displacement time graph for the two particles A and B are straight lines inclined at angles of 30 and 45 degrees with the time axis.what is the ratio of the velocities VA : VB ?

PLZ ANS AS SOON AS POSSIBLE ...........TOMMOROW IS MY EXAM

Answer 1

${\bold{\huge{\orange{\underline{answer:}}}}}$

${\bold{\large{\underline{step-by-step-explanation:}}}}$

$velocity = slope \: of \: line \: formed \: in \: displacement \\ \\ \frac{v}{s} \: time \: graph \: = tan \alpha \\ \\ v_{a} \div v_{b} = tan30 \div tan45 \\ \\ = \frac{1}{ \sqrt{3}} \div 1 \\ \\ = \frac{1}{ \sqrt{3} }$

$<b> Ratio of velocities =1:√3$
