Answer:
hey did you ever found the answer because i need help with this question too
Step-by-step explanation:
I think it would be .08, as 100 is equal to 10^2.
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

(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

/(2×10)=16km
Answer:
180 dollars
Step-by-step explanation:
.6 = 60%
multiply = "of"= ()
.6 (300) = 180
