A plane takes `t times10^(2)` seconds to fly around a square with side 3.5km when the wind is blowing steady at a speed `30sqrt(2)m/s` parallel to one of the diagonals of square.The velocity of plane in still air is 50m/s .Find t.

Find the time an aeroplane having velocity v takes to fly around a square with side a if the wind is blowing at a velocity u along one side of the square.\

How long will a plane take to fly around a square with side a with the wind blowing at a velocity u, in the two cases (a) the direction of the wind coincides with one of the sides (b) the direction of the wind coincides with one diagonal of the square. The velocity of the plane in still air is v gt u ..

A hydrogen is flying eastward with speed 12 m s^(-1) , when wind starts blowing from north to south with speed 5 m s ^(-1) what is the resultant velocity of balloon ?

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 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 ball is projected from a point on an inclined plane horizontally. It takes 1/(sqrt(2)) seconds to strike the plane. If the incline plane makes an angle of 30^(@) with horizontal then find the range of the ball on incline plane in meters [g=10m//s^(2)]

One day in still air, a motor-cyclist riding norht at 30m//s , suddenly the wind starts blowing Westward with a velocity 50m//s , then calculate the apparent velocity with which the motor-cylist will move

Bird is flying in north-east direction with v= 4sqrt2 m/s with respect to the wind and the wind is blowing from north to south with speed 1 m/s. Find the magnitude of the displacement of bird in 3 sec.

Rain is falling at the speed of 25sqrt3 m//s vertically. The wind blows west to east at a speed of 25 m/s. find the velocity of rain as experienced by a person standing on the ground.

A 400 m wide river is flowing from west to east at velocity 3m/s. A boat starts from one bank and it crosses the river along the shortest path. When it reaches the middle of river, wind starts blowing horizontally along north-east at a velocity sqrt(2) m/s . Due to this, the direction of rowing of boat has to be changed for the boat to move along the shortest path. If the velocity of boat in still water with no wind blowing is 5 m/s, then choose the correct option(s).
