In a harbour, wind is blowing at the speed of ` 72 km //h` and the flag on the mast of a boat anchored in the harbour flutters along the N-E` direction`. If the boat starts moving at a speed of ` 51 km// h` to the North, what is the direction of flag on the mast of the bat ?

In a harbour, wind is blowing at the speed of 72 km //h and the flag on the mast of a boat anchored in the harbiyr flutters along the N-E direction. If the boat starts moving at a speed of 51 km// h to the North, what is the direction of flag on the mast of the bat ?

A political party has to start its procession in an area where wind is blowing at a speed of 30 sqrt(2) km h^-1 and party flags on the cars are fluttering along north - east direction. If the procession starts with a speed of 40 km h^-1 towards north, find the direction of flags on the cars.

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. Now the boat enters in to river, which is flowing with a velocity of 2m//sec . Due north. The boat starts with zero velocity relative to the river and its constant acceleration relative to the river is 0.2m//sec^(2) due east. In which direction will the flag flutter at 10 seconds ?

A boat travels upstream at the speed of 20 km/h and downstream at the speed of 30 km/h. What is the speed of the boat.

A train 350 m long is moving at the speed of 20 km/h. It will cross a man coming from the opposite direction at the speed of 1 km/h in ?

A train 350 m long is moving at the speed of 20 km/h it will cross a man coming from the opposite direction at the speed of 1 km/h in:

A child in danger of drowning in a river is being carried downstream by a current that flows uniformly at a speed of 2.5 km//h. The child is 0.6 km from shore and 0.8 km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 20 km//h with respect to the water, what angle does the boat velocity v make with the shore? How long will it take boat to reach the child?

A ship is travelling due east at a speed of 15 km//h. Find the speed of a boat heading 30^@ east of north if it appears always due north from the ship.
