A boat is being rowed in a river. Wind is also blowing. Direction of velocity vectors of boat, water and wind in ground frame are as shown in diagram.

Mark the correct statement(s)

A

Direction in which boat is being steered may be represented by arrow leftarrow

B

Direction in which boat is being steered may be represented by arrow rightarrow

C

Direction in which a flag on the boat may flutter may be represented by arrow rightarrow

D

Direction in which a flag on the boat may flutter may be represented by arrow rightarrow

Text Solution

Verified by Experts

The correct Answer is:
A, C, D

The flag will flutter in the air relative to the boat i.e. in the direction `vec(v)_(wb)=vec(v)_(wind)-vec(v)_(boat)`

A boat is moving in direction -4hati+3hatj with ,a speed of 10 rn/s. Write velocity vector of boat in unit vector notation. Direction of motion of boat is along unit vector :

A 400 m wide river is flowing from west to east at velocity 3m/s. A boat starts from one bank and it crosses the river along the shortest path. When it reaches the middle of river, wind starts blowing horizontally along north-east at a velocity sqrt(2) m/s . Due to this, the direction of rowing of boat has to be changed for the boat to move along the shortest path. If the velocity of boat in still water with no wind blowing is 5 m/s, then choose the correct option(s).

At a harbour, a boat is standing and wind is blowing at a speed of sqrt(2)m//sec. due to which , the flag on the boat flutters along north - east.
