A cyclist has mass $85\text{ kg}$ and rides a bicycle of mass $20\text{ kg}$ . The cyclist rides along a horizontal road against a total resistance force of $40\text{ N}$ . Find the total work done by the cyclist in increasing his speed from $5\text{ m s}^{-1}$ to $10\text{ m s}^{-1}$ while travelling a distance of $50\text{ m}$ .
