Small Cannon Displacement Problem

Click For Summary
SUMMARY

The discussion centers on calculating the horizontal distance a projectile will travel when launched from a small cannon at a 50-degree angle above horizontal. Given parameters include an initial height of 1.08 meters, a time of flight of 0.452 seconds, and gravitational acceleration of -9.81 m/s². The initial horizontal velocity was determined to be 5.0885 m/s. Using the equations of motion, participants are tasked with predicting the projectile's landing distance from the cannon.

PREREQUISITES
  • Understanding of projectile motion equations
  • Knowledge of trigonometric functions, specifically tangent
  • Familiarity with kinematic equations
  • Basic algebra for solving equations
NEXT STEPS
  • Calculate projectile motion using the equation x = x_i + v_ix*t

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
