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 the flag on the the mast of the boat?

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.

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.

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 covers a distance of 14 km in 4 hours along the flow. What is the speed of the boat in still water, if the speed of the flow of water is 2 km/h?

If the speed of a boat in still water is 8 km/h and the rate of stream is 4 km/h, then find upstream speed of the boat.

When you are standstill holding a flag, the flag flutters in the direction of wind. When you start running the direction of fluttering of the flag changes to the direction of the wind relative to you. In all case a flag flutters in the direction of the wind relative to the flag. Winds is blowing uniformly due north everywhere with velocity 12 m/s. A car mounted with a flag starts running towards cast. after 9s from starts the flag flutters in 53^(@) north of west and after 16 s from the start the flag flutters in 37^(@) north of west. (a) Find velocity of the car 9 s after it starts. (b) Find velocity of the car 16 s after it starts. (c) If the car maintains uniform acceleration, find acceleration of the car.

Speed of a speed-boat when moving in the direction parallel to the direction of the current is 16 km/hr. Speed of the current is 3 km/hr. So the speed of the boat against the current will be (in km/hr)
