Kinematics of motion in a straight line — practice question
A cyclist moves on a straight road with constant acceleration. He goes through points $A$, $B$ and $C$. He takes $2$ seconds to cover each of the segments $AB$ and $BC$, and his speed at $B$ is $4.5\,\text{m s}^{-1}$. The length of $AB$ is $\frac{4}{5}$ of the length of $BC$.
