I also calculate the maximum height the ball reaches, which is 45 meters above the ground. Additionally, I discuss the effects of air resistance and other refinements to the model. I encourage viewers to engage with the concepts presented and consider how different factors might influence projectile motion. Please review the calculations and the assumptions made in the problem.
