Answer:
Height of the fighter plane =1.5km=1500 m
Speed of the fighter plane, v=720km/h=200 m/s
Let be the angle with the vertical so that the shell hits the plane. The situation is shown in the given figure.
Muzzle velocity of the gun, u=600 m/s
Time taken by the shell to hit the plane =t
Horizontal distance travelled by the shell =u
x
t
Distance travelled by the plane =vt
The shell hits the plane. Hence, these two distances must be equal.
u
x
t=vt
u Sin θ=v
Sin θ=v/u
=200/600=1/3=0.33
θ=Sin
−1
(0.33)=19.50
In order to avoid being hit by the shell, the pilot must fly the plane at an altitude (H) higher than the maximum height achieved by the shell for any angle of launch.
H
max

(90−θ)/2g=600

Step-by-step explanation:
The three-dimensional objects generated by rotating a two-dimensional (rectangular or triangular) object around one edge are:
- Rotation creates a cone
- Rotation creates a cylinder
- Rotation creates a sphere
<h3>What 3 dimensional figure are formed by rotating a triangle?</h3>
The first shape or object that is known to be formed is said to be a Cone In rotation a three-dimensional figure, the Axis is known to bisects triangle and what is formed by rotating a triangle is said to be a Cone.
Hence, The three-dimensional objects generated by rotating a two-dimensional (rectangular or triangular) object around one edge are:
- Rotation creates a cone
- Rotation creates a cylinder
- Rotation creates a sphere
