Q13MEnergy, Work and PowerFree sample

A cyclist is riding a bicycle along a straight horizontal road $AB$ of length $50\text{ m}$ . The cyclist starts from rest at $A$ and reaches a speed of $6\text{ m s}^{-1}$ at $B$ . The cyclist produces a constant driving force of magnitude $100\text{ N}$ . There is a resistance force, and the work done against the resistance force from $A$ to $B$ is $3560\text{ J}$ .

Find the total mass of the cyclist and bicycle.
