The wind is blowing due south with speed of 3m/sec. How fast should a car travel due east in order that the wind shall hasve a speed of 5m/sec relative to the car.

A car is going in south with a speed of 5m//s . To a man sitting in car a bus appears to move towards west with a speed of 2sqrt(6)m//s . What is the actual speed of the bus?

Ship A is moving towards south with speed 3m/s and ship B is travelling due west with speed 4m/s Find the velocity of ship B with respect to ship A

A person moves due east at speed 6m/s and feels the wind is blowing to south at speed 6 m/s. (a) Find actual velocity of wind blow. (b) If person doubles his velocity then find the relative velocity of wind blow w.r.t. man.

A car travels 8 m due north and then 10 m due east Calculate the displacement of the car .

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 ?

The captain of a plane wishes to proceed due west. The cruising speed of the plane is 245 m/s relative to the air. A weather report indicates that a 38.0 m/s wind is blowing from the south to the north. In what direction, measured with respect to due west, should the pilot head the plane relative to the air?

A source is moving with constant speed upsilon_(s) = 20 m//s towards a stationary observer due east of the source. Wind is blowing at the speed of 20 m//s at 60^(@) north of east. The source has frequency 500 H_(Z) . Speed of sound = 300 m//s . The frequency resgistered by the observer is approximately

A car is moving with speed 30m//sec on a circular path of radius 500 m . Its speed is increasing at the rate of , 2m//sec^(2) , What is the acceleration of the car

A plane moves in windy weather due east while the pilot the plane somewhat south of east. The wind is blowing at 50 km/h directed 30^(@) east of north, while the palne moves at 200 km/h relative to the wind . What is the velocity of the plane relative to the ground and what is the direction in which the pilot points the palne ?

A train(T) is running uniformly on a straight track. A car is travelling with constant speed along section AB of the road which is parallel to the rails. The driver of the car notices that the train is having a speed of 7 m//s with respect to him. The car maintains the speed but takes a right turn at B and travels along BC. Now the driver of the car finds that the speed of train relative of him is 13 m//s . Find the possible speeds of the car.
