Given:

Speed of swimmer [tex]V_{s}=0.6 m/s[/tex]

Width of the river [tex]=50m[/tex]

Speed of the water in river [tex]V_{w} =0.36m/s[/tex]

To find:

The direction in which he swimmer should swim in order to reach the exact opposite point.

Solution:

From the figure, lets assume that the swimmer starts swimming from [tex]O[/tex] with a speed [tex]V_{s}=0.6m/s[/tex]. According to the question, the swimmer wants to reach the point [tex]P[/tex] but, as we know, the river is flowing with a velocity [tex]V_{w}=0.36m/s[/tex].

If the swimmer swims in the direction [tex]OP[/tex], he will lose the trajectory of the path and miss the point [tex]P[/tex] by flowing in the direction of the river.

To cover this gap, the swimmer needs to swim in the direction opposite to the flow of the river at an angle θ with the horizontal.

Lets assume, the target point of the swimmer be the point [tex]O'[/tex] which makes an angle θ with the river. Hence, with the presence of the flow of river, swimmer reaches the required point [tex]P[/tex].

Now,

In Δ[tex]OAO'[/tex], we have, ∠[tex]AOO'=[/tex] θ, Hence,

[tex]cos[/tex]θ  [tex]=\frac{OA}{O'O}[/tex]

[tex]cos[/tex]θ  [tex]=\frac{0.36}{0.6}[/tex]

[tex]cos[/tex]θ  [tex]=0.6[/tex]

Hence,

θ [tex]=cos^{-1}(0.6)[/tex]

θ [tex]=53^{o}[/tex]

The swimmer needs to travel with an angle of [tex]53^{o}[/tex] with respect to the origin with the horizontal.

Final answer:

Hence, the swimmer should travel in the direction opposite to the flow of river at an angle of 53° with respect to the horizontal.
