Question

INTEXT EX
A boat is moving with velocity of 3i^+4j^ in
and water is moving with a velocity of -3i^-4j^
with respect to ground. Relative velocity of boat
with respect to water is:
(a) -6i^ – 8j^
(c) 8i^
(b) 6i^ +8j^
(d) 6i^​

Answer 1

Answer:

Hey mate your answer is

6î + 8 j^

Solution :-

Velocity of boat w.r.t. water (Vbw)

Vbw = Vb - Vw

Vbw = 3î + 4j^ - (-3î - 4 j^)

Vbw = 3î + 4j^ + 3î + 4j^

Vbw = 6î +8j^

hence velocity of boat w.r.t water is

6î + 8j^

Hope this will help uh!
