A man is walking toward east with a velocity of 8 km/h. Wind is blowing toward north - east at angle of `45^(@)`. To the man wind appears to blow of angle of `60^(@)` north of west.

For a man walking towards east with a velocity of "5km/hr" rain appears to fall vertically down.When the man begins to walk towards west with a velocity of "3km/hr" the rain appears to fall at an angle of 60^(0) to the vertical.The magnitude of velocity of the rain when the man stops walking is sqrt((139)/(N)) .Then N is equal to

A boat is moving towards south with veloctity 3 m//s with respect to still water and river is flowing towards east with velocity 3 m//s and the wind is blowing towards south-east with velocoity 3 sqrt2 m//s . The direction of the flag blown over by the wind, hoisted on the boat is :

A boat is moving towards east velocity 4 m/s w.r.t still water and river is flowing towards north with velocity 2 m/s and the wind blowing towards north with velocity 6 m/s. the direction of the flag blown over by the wind hpisted on the boat is

A man walks towards east with certain velocity. A car is travelling along a road which is 30^(@) west of north. While a bus is travelling in another road which is 60^(@) south of west. Find the angle between velocity vector of (a) man and car (b) car and bus (c) bus and man.

Calculate the distance travelled by the car, if a car travels 4km towards north at an angle of 45^(@) to the east and then travels a distance of 2km towards north at an angle of 135^(@) to the est.

A person travelling east wards at the rate of 4 km h^(-1) finds that the wind seems to blow directl from the borth . On dubling ins speed, the wind appears to come from 45^@ north of west. Find the actual velocity of the wind.

A bota has a velocity 4m//s towards east with respect to river is flowing north with velocity 2m//s Wind is blowing towards north with velocity 6m//s . The direction of the flag blown over by the wind hoisted on the boat is :

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 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.
