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 1.2m tall girl spots a balloon moving with the wind in a horizontal line at a height 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 sometime, the angle of elevation reduces 30°.Find the distance travelled by the balloon during the interval.

A 1.2m tall girl spots a ballon moving with the wind in a horizontal line at a height of 88.2m from a ground.The angle of elevation of the balloon from the eyes of the girl at any instant is 60^(0). After some time,the angle of elevation reduces to 30^(0). Find the distance travelled by the balloon during the interval.

A boy whose eye level is 1.3 m from the ground, spots a balloon moving with the wind in a horizontal line at same height from the ground. The angle of elevation of the balloon from the eyes of the boy at an instant is 60^(@) . After 2 seconds, the angle of elevation reduces to 30^(@) . If the speed of the wind is 29sqrt(3) m//s then find the height of the balloon from the ground.

A body is dropped from a balloon moving up with a velocity of 4 m//s , when the balloon is at a height of 120 m from the ground. The height of the body after 5 s from the ground is:

A girl is observing a bird sitting at a height of 500 m from the ground. The angle of elevation of the bird from the girl's eyes is 45^(@) at the initial position. After some time, the girl moves on the ground towards the bird by 50 m and bird flies away from her. At this point, the angle of elevation reduces to 30^(@) . Find the distance travelled by the bird. Take sqrt(3) = 1.73

A body is dropped from a balloon moving up wigh a velocity of 4 m s^(-2) when the balloon is at a height of 12.5 m from the ground. The height of the body after 5 s from the groumd is (g=9.8 ms^(-2)) .
