Projectile Motion Maybe Parametric equations?

Click For Summary
SUMMARY

The discussion revolves around solving a physics problem related to projectile motion, specifically question 4 from a problem set. The user successfully calculated the minimum velocity (Vmin) as 0.84 m/s but is struggling to determine the maximum velocity (Vmax). A contributor suggests using parametric equations to break the motion into x and y components and apply kinematics to find Vmax, similar to how Vmin was calculated.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with kinematic equations
  • Knowledge of parametric equations in physics
  • Basic skills in vector decomposition
NEXT STEPS
  • Study the derivation of kinematic equations for projectile motion
  • Learn how to apply parametric equations to solve physics problems
  • Practice vector decomposition techniques in projectile motion scenarios
  • Explore advanced topics in projectile motion, such as air resistance effects
USEFUL FOR

Students studying physics, educators teaching projectile motion concepts, and anyone looking to enhance their problem-solving skills in kinematics.

Hey I have a problem with question 4 of this problem set


http://www.physics.ubc.ca/~mattison/Courses/Phys170/p170-ps5.pdf Number 4.

I have found Vmin to be 0.84m/s which i know it is correct, but i cannot solve Vmax?

i thoguht you could maybe approach this question with 2 parametric equations? can anyone show me some hints toward this question?

Greatly appreciated.

You find Vmax EXACTLY the same way you find Vmin. Break the motion into xy components and use kinematics. How did you find Vmin?
