A projectile is lauched at some speed at an angle of 58 degrees and travels a range of 211 meters. The launch angle is then changed, but the projectile is fired at the same speed as the original case and also travels the same range of 211 meters. Find the maximum vertical displacement at 58 degrees, (ymax1), and find the maximum vertical displacement for the second angle (ymax2), and then find the difference between them in meters (diff = ymax1 - ymax2).
