Vvel = 10 m / s.
Vwind = 2 m / s.
Vv / ground -?
Since the speed of the cyclist Vwel and the speed of the headwind Vwind are oppositely directed, the speed of the cyclist relative to the ground with the headwind Vw / ground will be the difference between Vwind and Vwind.
Vv / earth = Vvel – Vwind.
Vv / earth = 10 m / s – 2 m / s = 8 m / s.
Answer: the speed of the cyclist relative to the ground with a headwind Vw / ground = 8 m / s.
