In the figure shown the initial velocity of boat (30kg) + person (15 kg ) is 2 m/. Find velocity of person w.r.t. boat so that velocity of boat will be 1 m/ in right (Neglect friction between boat and water)
(A) 3 m/* towards right
(B) 3 m/* towards left
(C) 4 m/* towards right
(D) 4 m/* towards left
