Ответ:
height = 3000m
Step-by-step explanation:
In order to calculate the height reached by the airplane, you first calculate the distance traveled by the airplane in one minute. The distance is given by:
v: speed of the airplane = 100m/s
t: time = 1 min = 60 s
you replace in the equation (1):
The distance traveled by the airplane while it is going up, can be considered as a hypotenuse of a rectangle triangle.
The angle at which the airplane started to fly was 30°. Then, you can use the following trigonometric relation to calculate the height:
hence, the height reached by the ariplane is 3000m
