Projectile Motion: Finding Initial Velocity

Click For Summary
SUMMARY

The discussion centers on the formula for calculating the range of a projectile, specifically R = Vo^2 x sin(angle) / g, where Vo represents the initial velocity and g is the acceleration due to gravity. It is clarified that Vo refers to the resultant velocity, not the individual components in the X or Y directions. Additionally, the range formula presented is noted to be incorrect in its current form, indicating the need for precise mathematical representation in projectile motion calculations.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with kinematic equations
  • Knowledge of trigonometric functions
  • Basic grasp of vector components
NEXT STEPS

Hello,

When trying to find initial velocity in Proyectile motion can I use the formula or Range: R=Vo^2 x sin angle / Gravity

The question is if the velocity I get through that equation will be the vector in X, Y or the resultant one?

Thanks

Hello, can you please help me with my question about the range,

thanks
 
Welcome to PF :smile:

Vo refers to the resultant velocity.

By the way, the range formula is not quite correct as written:
R=Vo^2 x sin angle / Gravity
