A river is flowing with velocity 5 km/hr relative to the ground
as shown in the figure. A boat starts from A and reaches the other bank
by covering shortest possible distance. Velocity of boat in still water
is 3 km/hr. The distance (in m) boat covers is s. The value


Show answer and solution
For drift to be minimum
[IMAGE] time taken by boat to cross the river = t
So, distance covered[IMAGE] TOPIC:Motion in a plane
SUB TOPIC:Relative motion







[IMAGE] time taken by boat to cross the river = t
