A swimmer wants to cross a river from point A to point B. Line AB makes an angle of 30° with the flow of the river. The magnitude of the velocity of the swimmer is the same as that of the river. The angle θ with the line AB should be _______°, so that the swimmer reaches point B.

Question diagram: A swimmer wants to cross a river from point A to point B . L
Answer:
30.00
Solution:

Both velocity vectors are of same magnitude therefore resultant would pass exactly midway through them θ=30°
