Question

A goose is flying due south at 20 km/hr, the goose is flying into a 15 km/hr due north wind. What is the gooses resultant velocity?

Answer 1

5 km/hr due south

Step-by-step explanation:

We need to subtract the two velocities due to the fact that they are in opposite directions (one due south and the other one due north). Then, for an observer located on earth, the goose will be flying at :

20 km/hr - 15 km/hr = 5 km/hr
