An airplane is observed by two persons travelling at 60 km/hour in two vehicles moving in opposite directions on a straight road. To an observer in one vehicle the plane appears to cross the road track at right angles while to the observer in the other vehicle the angle appears to be `45^(@)` . At what angle does the plane actually cross the road track and what is its speed relative to ground?

An airplane is observed by two observers traveling at 60 km h^-1 in two vehicles moving in opposite directions on a straight road. To an observer in one vehicle, the plane appears to cross the road track at right angles while to the other appears to be 45^@ . At what angle does the plane actually cross the road track and what is its speed relative to ground ?

Two persons A and B travelling at 60 km//hr^(–1) in their cars moving in opposite directions on a straight road observe an airplane. To the person A, the airplane appears to be moving perpendicular to the road while to the observe B the plane appears to cross the road making an angle of 45° . (a) At what angle does the plane actually cross the road (relative to the ground). (b) Find the speed of the plane relative to the ground.

There are two cosecutive kilometre posts on a straight road.From an aeroplane flying vertically above the road in between the two km.Posts the angles of depression of the two km.Posts are seen to be 45^@ and 60^@ At what height is the aeroplane flying at the moment of observation?

Consider a vehicle going on a horizontal road towards east. Neglect any force by the air. The frictional forces on the vehicle by the road
