Question

To a cyclist riding due west with a speed of 4 m/s a wind appears to

Answer 1

Answer:

The actual velocity of the wind blowing from south to west is, V = 3.08 m/s

Explanation:

Given data,

The velocity of the cyclist towards west, v = 4 m/s

The wind appears to blow from the south, U = 2 m/s

Let Ф be the angle formed by the direction of the wind with the west axis,

Therefore, the actual velocity of the wind is,

                                 V = (v - U) secФ

                                     = 2 sec Ф

Le the value of Ф = 30°, (The student may add the necessary value of Ф)

                                  V =  2(1.54)

                                   V = 3.08 m/s

Hence, the actual velocity of the wind blowing from south to west is, V = 3.08 m/s
