$5 : 9$

Vedclass · Answer

According to problem
Distance travelled by body $\mathrm{A}$ in $5^{	ext {th }}$ sec and distance travelled by body $\mathrm{B}$ in $3^{\mathrm{rd}}$ sec. of its motion are
equal.
$0+\frac{a_{1}}{2}(2 	imes 5-1)=0+\frac{a_{2}}{2}[2 	imes 3-1]$
$9 a_{1}=5 a_{2} \Rightarrow \frac{a_{1}}{a_{2}}=\frac{5}{9}$

A body $A$ starts from rest with an acceleration $a_1$ . After $2\ seconds$ , another body $B$ starts from rest with an acceleration $a_2$ . If they travel equal distance in the $5th\ second$ , after the start of $A$ , then the ratio $a_1$ : $a_2$ is equal to
