The true velocity of the wind which is the resultant velocity of the wind is determined as 43.1 km/h.
Resultant velocity of the wind
The true velocity of the wind is the resultant velocity of the wind when it collides with the motor cyclist and it is calculated as follows;
R² = 50² + 60² - 2(50 x 60)cos(45)
R² = 1857.36
R = √1857.36
R = 43.1 km/h
Thus, the true velocity of the wind which is the resultant velocity of the wind is determined as 43.1 km/h.
