Energy, work and power — practice question

A cyclist travels on a straight horizontal road $AB$ of length $50\text{ m}$. The cyclist begins from rest at $A$ and reaches a speed of $6\text{ m s}^{-1}$ at $B$. The cyclist applies a constant driving force with magnitude $100\text{ N}$. A resistance force is present, and the work done against this resistance from $A$ to $B$ is $3560\text{ J}$.
