Projectile Question -- Kicking a soccer ball through two holes in two walls....

Click For Summary
SUMMARY

The discussion centers on calculating the initial velocity required for a soccer ball to pass through two holes in walls, utilizing projectile motion equations. The key equations involved are dx = v1(cos theta) * t and dy = v1(sin theta) * t - 0.5at^2. The participant initially struggled with setting up the system of equations based on the x and y displacements but ultimately resolved their issue and successfully solved the problem.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with trigonometric functions in physics
  • Ability to set up and solve systems of equations
  • Knowledge of basic kinematic equations
NEXT STEPS
  • Study the derivation of projectile motion equations
  • Practice solving problems involving multiple variables in physics
  • Learn about the effects of air resistance on projectile motion
  • Explore advanced kinematic simulations using software tools
USEFUL FOR

Students studying physics, educators teaching projectile motion concepts, and anyone interested in solving real-world problems involving kinematics.

Homework Statement



Find the initial velocity for the above soccer kick. Note that ball must cross the 2 points in the diagram within the two walls.

Linked below is the diagram

Homework Equations


dx = v1(cos theta) * t
dy = v1(sin theta) * t - 0.5at^2

The Attempt at a Solution


I tried using the displacements in the x and y and making a system of equations out of them. But after a while, I just got stuck.

Any help would be greatly appreciated

Can you show what you did so far using the x and y displacements? Just saying "I tried but I got stuck" really doesn't give us anything to go on to help you out.

Nevermind, I ended up finding my mistake, and solving the system.
