Projectile Motion of artillery

In summary, the equations given are used to find the time of travel and angle of the artillery given a fixed barrel velocity, elevation of the piece of artillery, target distance, and target elevation. The equations used are y_0 = te - e, x = v_0 * cos(a) * t, and y = y_0 + v_0 * sin(a) * t - 0.5 * g * t^2. However, it may be difficult to solve for both a and t simultaneously. It is recommended to use tex brackets for a neater presentation of the equations.

Given:
A fixed barrel velocity, [tex]v_{0}[/tex]
An elevation of the piece of artilery, e
Target distance, x
Target elevation, te

Find:
time of travel, t
angle of the artilery, a

Equations:
[tex]y_{0}[/tex] = te - e

x = [tex]v_{0}[/tex] * cos(a) * t
y = [tex]y_{0}[/tex] + [tex]v_{0}[/tex] * sin(a) * t - 0.5 * g * [tex]t^{2}[/tex]

If you try solving these for a and t, it gets ugly. Is there an equation I am missing or another way around this?

You're y_0 seems wrong. At t=0 the elevation should be e should it not? Other than that it looks good, two equations, two variables therefore solvable.

tip:put your entire equations between tex brackets it will look at a lot better.

I would suggest using the quadratic formula to solve for t in the second equation, and then plugging that value into the first equation to solve for a. This will give you a value for the angle of the artillery and the time of travel. Alternatively, you could also use numerical methods or a computer program to solve for these values. It is also possible that there may be other equations or methods specific to projectile motion of artillery that could simplify the process. It would be beneficial to consult with experts in the field or conduct further research to find more efficient methods for solving this problem.
 

1. What is projectile motion?

Projectile motion is the motion of an object through the air in a curved path due to the influence of gravity. It is often seen in objects such as artillery, baseballs, and even falling objects.

2. How does the angle of launch affect the projectile motion of artillery?

The angle of launch, also known as the angle of elevation, plays a crucial role in the projectile motion of artillery. A higher angle of launch will result in a longer flight time and a higher maximum height, while a lower angle of launch will result in a shorter flight time and a lower maximum height.

3. What is the relationship between the initial velocity and the range of a projectile?

The initial velocity of a projectile, along with the angle of launch, determines the range of the projectile. The greater the initial velocity, the greater the range of the projectile will be. However, if the angle of launch is too low, the range will decrease even with a high initial velocity.

4. How does air resistance affect the motion of artillery projectiles?

Air resistance, also known as drag, can have a significant impact on the motion of artillery projectiles. It can decrease the range and height of the projectile, as well as change the shape of the trajectory. To account for air resistance, scientists use complex mathematical equations to calculate the trajectory of a projectile.

5. What is the difference between horizontal and vertical projectile motion?

Horizontal projectile motion refers to the motion of an object moving parallel to the ground with a constant horizontal velocity and a downward acceleration due to gravity. Vertical projectile motion, on the other hand, refers to the motion of an object moving straight up or down with a constant vertical velocity and a downward acceleration due to gravity.
