Question
Two persons of masses 40 kg and 60 kg are sitting at the midpoint of a 12 m long boat (140 kg) standing still in water. Now they move to the opposite ends of the boat then distance travelled by boat in water is (neglect friction):-
Options
A.100 cm
B.50 cm
C.25 cm
D.200 cm
Solution
Let the distance travelled by boat is d.
60 (6 - d) = 40 (6 + d) = 140 d
d =
m = 50cm
60 (6 - d) = 40 (6 + d) = 140 d
d =
m = 50cmCreate a free account to view solution
