Homework Help Overview

The discussion revolves around a projectile motion problem where the launch point is higher than the target point. The original poster provides specific values for distance, velocity, gravity, and launch height, seeking to determine the launch angle, theta.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the importance of analyzing the motion along the independent x- and y-axes, suggesting that this method simplifies the problem. There is also mention of a source for the equation used by the original poster.

Discussion Status

The conversation is ongoing, with participants exploring different analytical approaches to the problem. Some guidance has been offered regarding the separation of axes for analysis, but no consensus has been reached on the best method to solve for theta.

Contextual Notes

The original poster expresses difficulty with physics and trigonometry, indicating a potential lack of familiarity with the concepts involved in projectile motion. There is also a reference to an external source for the equation, which may imply varying interpretations of the problem setup.

Homework Statement



Hi to all guys i am not good in physics and trigonometric I tried to do a projectile system.My launch point is higher than target point.I know the velocity v, target_distance d, gravity g,Launch_height_y y0.I added a image that shows the equation.I tried my own but not solved the equation.Please some one help me

d = 30,v = 22 , g = 9.8 ,y0 = 2

I wants to find the theta(angle)

Not sure how you got the equation but ut would be best to analyse along the independent x- and y-axes.One is accelerated and other is simple non-accelerated one.
 
Of course it is right. What I meant was analysis along x- and y-axes separately is much simpler(that's how they got the formula).
