Small Cannon Displacement Problem

In summary, a small cannon was set at 0 degrees above horizontal and shot a projectile 1.08 meters above the floor. It took 0.452 seconds to hit the floor and traveled a horizontal distance of 2.3 meters. The acceleration of gravity was -9.81 meters per second squared and the resulting velocity was 5.0885 meters per second. However, when the cannon was angled 50 degrees above horizontal, the problem was to predict where the ball would hit the ground. The equations needed for this problem are x = x_i + v_ix*t and y = y_i + v_iy*t + a*t^2/2, and the tangent of theta is also important. For more information and

I had a small cannon on a desk where the projectile was shot out at 1.08 meters above the floor. The projectile's time taken to hit the floor was 0.452 seconds. The cannon is set to 0 degrees above horizontal. The horizontal distance traveled is 2.3 meters. Acceleration is gravity or -9.81 meters per seconds squared. we found velocity to be 5.0885 meters per second.

Here's where the real problem comes in. Our teacher gave us a new angle to shoot the ball and we must predict where the ball will hit on the ground. Our angle was 50 degrees above horizontal. So how far away from the cannon does the ball end up? Please tell me your work, equations used, and final answer. Thank you.

You will need the following equations and know how to use them,

x = x_i + v_ix*t
y = y_i + v_iy*t + a*t^2/2
 

FAQ: Small Cannon Displacement Problem

What is the "Small Cannon Displacement Problem"?

The "Small Cannon Displacement Problem" is a physics problem that involves calculating the displacement of a small cannon due to recoil, taking into account the mass of the cannon, the mass of the projectile, and the initial velocity of the cannon and projectile.

Why is the "Small Cannon Displacement Problem" important?

The "Small Cannon Displacement Problem" is important because it helps us understand the concept of momentum conservation and its application in real-world scenarios. It also has practical applications in fields such as engineering and ballistics.

What are the key factors that affect the displacement of the cannon in this problem?

The key factors that affect the displacement of the cannon in this problem are the mass of the cannon, the mass of the projectile, and the initial velocity of the cannon and projectile. These factors determine the momentum of the system and ultimately the displacement of the cannon.

How do you solve the "Small Cannon Displacement Problem"?

To solve the "Small Cannon Displacement Problem", you need to use the principles of momentum conservation and apply the equation: m1v1 + m2v2 = (m1 + m2)v, where m1 and v1 are the mass and velocity of the cannon, m2 and v2 are the mass and velocity of the projectile, and v is the final velocity of the system. Using this equation, you can calculate the displacement of the cannon by rearranging it as: v = (m1v1 + m2v2) / (m1 + m2).

What are some real-world applications of the "Small Cannon Displacement Problem"?

The "Small Cannon Displacement Problem" has various real-world applications, such as in the design of recoil systems in firearms, the calculation of the recoil of a rocket after launch, and the engineering of impact-resistant structures. It is also used in the field of ballistics to predict the trajectory of projectiles fired from cannons or guns.
