A cyclist is going in a straight line at a uniform velocity 18 km/h. The resistance force can be expressed as force \[k{{v}^{2}}\]where \[k=0.8\] where velocity is in m/s and unit of force is newton. The mass of the cyclist with the bicycle is 100 kg. Neglect the rolling resistance force. If the power of the cyclist during the ride is \[{{10}^{x}}\]watt, then what is x?
