We are creation a MATLab simulation of a projectile motion equation of a ping pong ball being launched by a slingshot. I have completely figured out how my script needs to be written, but each time I run it it's giving me weird answers. Please Help!!

%% Horz Travel Dist (RB1)

clc;clear;

d = (.125:.125:4); %Distance matrix

d = d*.0254; %coverting inches to meters (m)

angle = input('What Angle is of Interest? ');

angle = angle*pi/180; % Converts Degrees to Radians

k = (.5292); % Spring Constant (F)

m = .0027; % Mass of the ball (kg)

g = 9.80665; %acceleration due to gravity (m/s^2)

A = (k*d)/m; %non-linear spring acceleration (m/s^2)

Voy = sqrt((2*d*sin(angle)).*(A*sin(angle)-g)); %Y Initial Velocity

Vox = cos(angle)*sqrt(2*d.*A); %X Initial Velocity

n = 1;

while (n <= 32) % Loop that computes the time for the ball to travel

    a =-4.903325;
    b = Voy(n);
    c = 0;
    e = [a, b, c];
    T(:,n) = roots(e);
    t(n) = max(T(:,n));
    n = n+1;
end

n = 1;

while (n <= 32) % Loop computes the Distance traveled by the ball

    x(n) = Vox(n)*t(n)*cos(angle);
    n = n+1;
end

disp(x/.3048) % Converts meters to feet
