Question

Бомбардировщик пикирует на цель под углом 60градусов к горизонту со скоростью 900 км/ч и сбрасывает бомбу на высоте 600м. На каком расстоянии от цели по горизонтальному направлению надо скинуть бомбу, чтобы она попала в цель? Скиньте пожалуйста решение и ответ) Заранее благодарю!)

Answer 1

Дано: α=60°
V=900км/ч=250м/с
h=600м
Найти:
L-?м
Решение:
Уравнения в проекциях на оси X и Y:
Ox: x=V0*cosα*t
Oy: y=V0*sinα*t+(gt²)/2
Ускорение свободного падения сонаправлено с Vx(видно из чертежа)
h=V0*sinα*t+(gt²)/2
gt²+2V0*sinα*t-2h=0
D(дискриминант)=4V0²*sin²α+8gh
t=(-2V0*sinα+-√4V0²*sin²α+8gh)/2g (один корень остаётся отрицательным, остаётся следующий)
t=(-2V0*sinα+√4V0²*sin²α+8gh)/2g
t=(-2*250*(√3/2)+√(4*250²*(√3/2)²+8*10*600))/2*10
t=(-250*√3+√(25000*0.75+48000))/20
t=(-250*√3+√(187500+48000))/20
t=(-250*√3+√235500)/20
t=(-250*1.73+485)/20
t=(-433 + 485)/20
t=52/20=2.6c
L=V0*cosα*t
L=250*0.5*2.6=325м
Ответ: 325м

Answer 2

Problem Analysis

We are given the following information: - The bomber is diving at an angle of 60 degrees to the horizontal. - The bomber's speed is 900 km/h. - The bomb is dropped at a height of 600 meters.

We need to find the horizontal distance from the target at which the bomb should be dropped in order to hit the target.

Solution

To solve this problem, we can break it down into two components: the horizontal component and the vertical component.

# Horizontal Component

The horizontal component of the bomber's velocity is given by the formula:

Horizontal Velocity = Total Velocity * cos(Angle)

where: - Total Velocity = 900 km/h - Angle = 60 degrees

Using this formula, we can calculate the horizontal velocity of the bomber.

# Vertical Component

The vertical component of the bomber's velocity is given by the formula:

Vertical Velocity = Total Velocity * sin(Angle)

where: - Total Velocity = 900 km/h - Angle = 60 degrees

Using this formula, we can calculate the vertical velocity of the bomber.

# Time of Flight

The time of flight can be calculated using the formula:

Time of Flight = Height / Vertical Velocity

where: - Height = 600 meters - Vertical Velocity = calculated in the previous step

Using this formula, we can calculate the time of flight of the bomb.

# Horizontal Distance

The horizontal distance can be calculated using the formula:

Horizontal Distance = Horizontal Velocity * Time of Flight

where: - Horizontal Velocity = calculated in the first step - Time of Flight = calculated in the previous step

Using this formula, we can calculate the horizontal distance from the target at which the bomb should be dropped.

Calculation

Let's calculate the values step by step.

# Horizontal Component

Horizontal Velocity = 900 km/h * cos(60 degrees)

# Vertical Component

Vertical Velocity = 900 km/h * sin(60 degrees)

# Time of Flight

Time of Flight = 600 meters / Vertical Velocity

# Horizontal Distance

Horizontal Distance = Horizontal Velocity * Time of Flight

Answer

The bomb should be dropped at a horizontal distance of (Horizontal Distance) from the target in order to hit the target.
