SUMMARY

The discussion focuses on solving for the initial velocity (v0) using two equations: A0*v0=Av and v^2=v0^2+2gh. The solution derived is v0=[2gh*A^2/(A0^2-A^2)]^1/2. Participants emphasize the importance of algebraic manipulation, specifically eliminating the variable v through substitution to arrive at the solution. The conversation highlights the straightforward nature of the algebra involved in this physics problem.

PREREQUISITES
  • Understanding of basic algebraic manipulation
  • Familiarity with kinematic equations in physics
  • Knowledge of variables A0, A, g, and h
  • Ability to perform substitutions in equations
NEXT STEPS
  • Study the derivation of kinematic equations in physics
  • Practice algebraic substitution techniques
  • Explore the implications of variable elimination in problem-solving
  • Review examples of solving for variables in physics equations
USEFUL FOR

Students studying physics, particularly those tackling kinematics and algebraic problem-solving, as well as educators looking for examples of teaching these concepts effectively.

Homework Equations




how do u solve for v0 from these two equations 1.)A0*v0=Av and 2.)v^2=v0^2+2gh...

The Attempt at a Solution




the sol is v0=[2gh*A^2/(A0^2-A^2)]^1/2... but i don´t know to get it... please help

It should be straightforward algebra. Eliminate v from one of your equations using a substitution from the other...
 
got it now... thank you
