Trajectory of a Projectile that must clear an obstruction

Click For Summary
To determine the vertical component of velocity (Vy) for a projectile that must clear an obstruction while still hitting a target, the projectile's motion can be modeled using kinematic equations. The key is to establish a relationship between the horizontal (Vx) and vertical components of velocity, considering the projectile's trajectory must pass through specific points: the starting point, the height of the obstruction, and the target landing point. The equations for horizontal and vertical motion can be combined to express Vy in terms of Vx while ensuring that the projectile's height exceeds the obstruction's height at the corresponding horizontal distance. This approach allows for solving the problem without relying heavily on trigonometry, focusing instead on the relationships defined by the projectile's path. Ultimately, the goal is to find a suitable Vy that satisfies both the clearance of the wall and the landing position.

Now I have my parabolic equation. From this, I find the tangent line at point ##(x_1,y_1)## by taking the derivative of my equation, finding the slope, pluggin that back, etc. From here, I can calculate an angle ∅ of the initial trajectory.

What do you do in the "ect"? I'm trying to make a tennis game and i was trying to understand how dows this works but it is hard... If you could help me I would appreciate it very much!

Are you the guy that commented on my YouTube video?

The "etc" part is solving for Y (which gives you the magnitude of the force needed). I will try to zip my Unity project up and send it to you somehow. It will be later today or tomorrow. I am having surgery in about 2 hours, so I will be in pain for a while.

I don't wat to pressure you and hope you recovered fine but are you still going to share your project? It would help me a lot!

Could you just say anything please?

you didn't replied for a month... if you see this pleeeeese send me your Unity progect to joaonunodiasleitao@gmail.com! I tried to recriate it but i coundn't make the same effect... Hope you recovered well from your surgery!
