Question

A police car is traveling in a straight line with a constant speed $v$. A truck traveling in the same direction with constant velocity. Find velocity(acceleration$=0.3m/s^2$)

Answer 1

$(\frac{3v}{2}-v)10=\frac{v}{2}\times 10m$

acceleration $3m/s^2$

$\frac{v}{2}\times 10+\frac{3v}{2}\times 10=v\left(10\right)+\frac{1}{2}\left(3\right)\left({10}^2\right)$

$=20v=10v+150$

$v=15{ms}^{-1}$
