Question
A man is walking in the rain with the speed of 4 m/s in the west direction, and it is raining vertically downwards with the speed of 4 m/s. Find the direction of the person’s umbrella so that the rain does not wet him.
- 30
- 60
- 45
- 0
Hint:
45°
The correct answer is: 45
Therefore, a person should hold his umbrella at an angle of 45° to the verticle so that the rain does not wet him.
