7. The power output of a cyclist moving at a constant speed (level ground) of 6.0 m/s is 120W. a) What is the force of air resistance and friction acting? b) By bending low over the handle bars, the cyclist reduces the resistance to 18N. If they maintain a power output of 120W, what will their speed be?
