A 1.2 m tall girl spots a balloon moving with the wind in a horizontal line at a height of 88.2 m from the ground. The angle of elevation of the balloon from the eyes of the girl at any instant is `60o`. After some time, the angle of elevatio

A 1.2 m tall girl spots a ballon moving with wind in a horizontal line at a height of 88.2 m from the ground. The angle of elevation of the balloon from the eyes of the girl at any instant is 60^(@) . After some time, the angle of elevation reduces to 30^(@) . Find the distance travelled by the balloon during the interval.

A body is dropped from a balloon meving up wigh a velocity of 4 m s^(-2) when the balloon is at a height of 12.5 m from the ground. The distance of separation between of separation between the body and the balloon after 5 is.

A balloon is rising vertically upwards. An an instant, an observation on the ground, whose distance from the balloon is 100 meters, sees the balloon at an angle of elevation of 30^(@) . If the balloon rises further vertically to a point where the angle of elevation as seen by the observer is 45^(@) , then its height (in meters) from the ground is ("Take "sqrt3=1.73)
