1. The problem statement, all variables and given/known data If the projectile is launched and lands at the same level. Then the angle is the same at launch and landing, correct? And if the projectile is launched from a different height, then the angle of launch is different than the angle of landing? In such a situation, if it says that a projectile hits the ground at an angle of 45 degrees, that tells you that final horizontal and vertical components are equal, right? But in calculating those components, you would still use the launch angle? 2. Relevant equations x= vocos(theta)t vfy= vosin(theta)-gt 3. The attempt at a solution I have outlined my views above. I just need to confirm that I am thinking about the situations correctly.
