Hi,
If the input is final distance and according to you it is the Max distance (assuming you are talking about max distance that can be covered ) then we can directly say that the projection angle is 45 degrees ( using basic physics ) and from there we can easily calculate the intial velocity using the below code
function [initial_velocity, launch_angle] = projectileMotion(max_distance)
gravity = 9.81;
initial_height = 0; % Assume the projectile starts from the ground level
launch_angle = 45;
% Convert launch angle to radians
launch_angle_rad = deg2rad(launch_angle);
% Calculate the initial velocity required to reach the max distance
initial_velocity = sqrt((max_distance * gravity) / sin(2 * launch_angle_rad));
end
Hope this helps
