Question

find direction in which swimmer should swim to cross river along the line ab , swimmer can swim in still water with speed of 8km/h
​

Answer 1

Answer:

Vsr= 2m/s

Vrg= root 3m/ s

Sin theta= Vrg/Vsr

Angle = 60

Therefore required angle is 90+ 60= 150

Answer 2

Answer:

Vsr= 2m/s

Vrg= root 3m/ s

Sin theta= Vrg/Vsr

Angle = 60

Therefore required angle is 90+ 60= 150

Answer 3

Answer:

Vsr= 2m/s

Vrg= root 3m/ s

Sin theta= Vrg/Vsr

Angle = 60

Therefore required angle is 90+ 60= 150
