A man can swim at a speed of 3kmph in stilll water. he wants to cross a 500 m wide river flowing at 2kmph. He keeps himself always at an angle of 1200 with the river flow.
a> Find the time taken to cross the river.
b> At what point on the opposite bank will he arrive?
My doubt occurs in the 2nd part of the question.
the answer of the second part is 96 m on the right side.
---------------------------------------------------------------------------------------------------
here is my solution.
the time taken comes out to be 1/3\( \sqrt{3} \)
2nd part of the answer
step 1: diagram (click here)
step 2: click
step 3 : diagram
step 4: the displacement along the direction of Vsg is
speed * time
= \( \sqrt{19} \) * (1/3\( \sqrt{3} \))
= 0.83 km.

The answer of my solution is wrong.
Can anyone please tell me where I am going wrong?
