Question

A river 400 m wide is flowing at a rate of 2 m/s. A
man swims with a velocity of 8 m/s with respect to
water, in a direction perpendicular to river. What is
the drift, when the reaches opposite bank? Vy
(1) 40 m
(2 80 m
(3) 100 m
(4) 200 m​

Answer 1

Answer:

Hey mate your answer will be

100 m

Explanation:

width of river = 400 m

swimming speed of man = 8 m/s

Time taken to cross River =

$\frac{distance}{time}$

$\frac{400}{8} = \: 50 \: sec$

Horizontal displacement due to river speed =

$speed \times time$

$2 \times 50 = 100 \: m$

Hope this will help uh!

Answer 2

Answer:

100m

Explanation:

Time = 400m/(8m/s) = 50 s

Drift = 2*50 = 100 m
