I'm having major problems figuring this one out. The question is from the book, yet their are no sample problems and a handful of given formulas. I've played around with the formulas with substitution, etc and I've end up with the wrong answer. Given: Angle of projectile fired and final displacement along X axis. angle = 25 degrees final displacement of x = 301.5 m accleration = -9.81m/s^2 Find: Maximum height of Y. any ideas how I can manipulate the standard formulas of projectile motion to solve for this problem?
