The discussion revolves around the analysis of projectile motion, specifically examining the angle of a projectile at one-fourth of its flight time compared to its launch angle. The problem requires an algebraic approach without numerical values, focusing on the relationship between the projectile's velocity components and the angles involved.
The discussion is ongoing, with participants providing insights into the nature of projectile motion and the mathematical relationships involved. Some participants have suggested clarifying the distinction between initial and subsequent angles, while others have raised questions about the equations used to describe the motion. There is a mix of interpretations regarding the problem setup and the information provided.
Participants note that the problem lacks specific numerical values and that the professor's instructions were not fully conveyed, leading to confusion about the application of formulas and the definitions of variables. There is an emphasis on solving the problem symbolically and understanding the components of motion in both horizontal and vertical directions.
No, you have no way to find out the launch angle. It is one of the inputs to the question. Just leave it as an unknown, ##\theta_0##. Rewrite your equation in post #28 using ##\theta_0## and ##v_0## as appropriate... then you are done.jeff12 said:Okay, so then am I suppose to find the launch angle first and then find the angle at another time after?
