two cars of the same mass are moving with velocities v1 and v2 resp

1.	two cars of the same mass are moving with velocities v1 and v2 respectively if they are stopped by supplying the same braking power in time t1 and t2 respectively then v1v2 is1) t1t2 2) t12t22 3) mt1t2 4) √t1t2
Answer» two cars of the same mass are moving with velocities $v_{1}$ and $v_{2}$ respectively if they are stopped by supplying the same braking power in time $t_{1}$ and $t_{2}$ respectively then $\frac{v_{1}}{v_{2}}$ is 1) $\frac{t_{1}}{t_{2}}$ 2) $\frac{{t_{1}}^{2}}{{t_{2}}^{2}}$ 3) $m \frac{t_{1}}{t_{2}}$ 4) $\sqrt{\frac{t_{1}}{t_{2}}}$

two cars of the same mass are moving with velocities v1 and v2 respectively if they are stopped by supplying the same braking power in time t1 and t2 respectively then v1v2 is1) t1t2 2) t12t22 3) mt1t2 4) √t1t2

Answer»

two cars of the same mass are moving with velocities $v_{1}$ and $v_{2}$ respectively if they are stopped by supplying the same braking power in time $t_{1}$ and $t_{2}$ respectively then $\frac{v_{1}}{v_{2}}$ is

1) $\frac{t_{1}}{t_{2}}$

2) $\frac{{t_{1}}^{2}}{{t_{2}}^{2}}$

3) $m \frac{t_{1}}{t_{2}}$

4) $\sqrt{\frac{t_{1}}{t_{2}}}$
