A river of width 'd' with straight parallel banks flows due North with speed u. A boat, whose speed is v relative to water, starts from A and crosses the river. If the boat is steered due West and u varies with y as `u=(y(d-y)v)/d^(2)` then answer the following questions.

Absolute velocity of boat when it reaches the opposite bank is

A. `4/3 v`, towards East
B. v, towards West
C. `4/3 v`, towards West
D. `vec(v)`, towards East

A

`4/3 v`, towards East

B

v, towards West

C

`4/3 v`, towards West

D

`vec(v)`, towards East

Text Solution

Verified by Experts

The correct Answer is:
B
At `y=d, u=0` so adsolute velocity of boat=v towards West
