A steamer is moving due east with 36 km/h.To a man in the steamer the wind appears to blow at 18km/h due north.The speed of the wind is (A) 5sqrt(5)ms^(-1) (B) 5ms^(-1) (C) 5sqrt(2)ms^(-1) (D) 10ms^(-1)

A car is moving towards east with a speed of 25 km h^-1 . To the driver of the car, a bus appears to move towards north with a speed of 25 sqrt(3) km h^-1 . What is the actual velocity of the bus ?

A man travelling towards east at 8km/h finds that the wind seems to blow directly from the north On doubling the speed,he finds that appears to come from the north-east.Find the velocity of the wind.

To a person travelling due East with velocity u the wind appears to blow from an angle alpha North of East. When he starts travelling due North with velocity 2 u,the wind appears to blow from an angle beta North of East. Find the true direction of the wind.

A ship is travelling due east at 10 km/h. A ship heading 30^(@) east of north is always due north from the first ship. The speed of the second ship in km/h is

A person travelling eastward with a speed of 3 kmh^(-1) finds that wind seems to blow from north. On doubling his speed, the wind appears to flow from north-east. Find the magnitude of the actual velocity of the wind.

Assertion: An observer is moving due east and wind appears him to blow from north. Then the actual direction of air blow must be towards south-east Reason: vecV_(R)=vecV_(A)-vecV_(M) where vecV_(R) is the relative velocity of wind w.r.t. man. vecV_(A)= actual velocity of wind (w.r.t. ground) and vecV_(M)= velocity of man w.r.t. ground.
