An air craft attempt too fly due north at 100 kmh^-1. If the wind blows against it from east to west at 60 kmh^-1, its resultant velocity is

Correct Answer: Option C

Explanation:

R² = 100² + 60²

10000 + 3600 = 13600

R = âˆš13600 = 117km

60kml & = tan = 60/100

tan^-1 0.6

= 31^o west of the North

117km N31^ow
