Two cars start off to race with velocities 4m/s and 2 m/s and travel in straight line with uniform acceleration $1\; m/s^2$ and $2 m/s^2$ respectively. If they reach the final point at same time, then the length of path is

\[(a)\; 30 m \quad (b)\;32 m \quad (c)\;20 m \quad (d)24 m \]

Can you answer this question?

$s=4t+\large\frac{1}{2}$$(1)t ^2$
Therefore $ s=4 (4)+\large\frac{1}{2}$$(1) 4^2$
Hence d is the correct answer
