Problem

A cyclist maintains a constant power output of

300\,\text{W}

while riding at a steady speed of

6\,\text{m/s}

along a horizontal road. (a) Calculate the magnitude of the total resistive force (mainly air resistance and rolling friction) acting on the cyclist. (b) How much work is done against these resistive forces in

10\,\text{s}

of such motion?
