MATLAB Projectile Motion Problem : Plot Trajectory of Projectile from launch to max height in MATLAB (restricted domain/range plots based off max height and t_end)

PLEASE HELP WILL RATE GREAT!! I am new to coding and this wasn't explained by substitute teacher! show all code able to copy and paste please! It is DUE in a COUPLE OF HOURS! Thanks so much!

Revise code so that t_end is general --- i.e. calculated from theory Hardcode all inputs (like Launch angle (q), Initial velocity (V0), Initial Position (y0) no need to prove you can do user input here Make Certain that comments are best ever and that appropriate use of sections is included Plot the trajectory of the projectile Use subplot to make plots of (y vs. x), (y vs. t) and (x vs. t) Use sprintf (or other) to add key values in to title Use appropriate titles for plots and axes Publish your output in PDF format

THIS IS MY CODE SO FAR BUT IT DOES PLOT ANYTHING in the figures.

clc; clear all workspace; format compact; format long g; %This is where user may input Initial Velocity (m/s), and Initial Height (m)%

%Hardcoded in%

y0 = 0;

V0 = 45;

%This is where user may input Launch Angle in Degrees%

%Hard coded in%

angledegree = 45;

anglerad = (angledegree*pi)/180;

ymax = (V0^2*(sin(anglerad))^2)/19.62;

%t_end should be auto calcuated based off of max height and then doesnt plot or for loop any further of the trajectory.%

t_end = (2*V0*sin(anglerad))/9.81;

g = -9.81; t = 0:.1:t_end ; Ay= g; numberOfAngles = length(anglerad); time=length(t_end); for i = 1 : time thistime = t(i); xVelocity = V0 * cos(anglerad); yVelocity = V0 * sin(anglerad); x = xVelocity .* thistime ; y = yVelocity .* thistime + (1/2) * Ay .* thistime.^2 + y0; subplot(2,2,1); plot(x,y); caption = sprintf('Angle = %.3f radians = %.2f degrees ', ... angledegree, anglerad*180/pi); title('y(t) vs. x(t)'); xlabel('distance (meters)'); ylabel('height (meters)'); grid on; ylim([0 ymax]) xlim([0 t_end]) subplot(2,2,2); plot(t_end,y); caption = sprintf('Angle = %.3f radians = %.2f degrees ', ... angledegree, anglerad*180/pi); title('time vs. y(t)'); ylabel('height (meters)'); xlabel('time (seconds)'); grid on; ylim([0 ymax]) xlim([0 t_end]) subplot(2,2,3); plot(t_end,x); caption = sprintf('Angle = %.3f radians = %.2f degrees ', ... angledegree, anglerad*180/pi); title('time vs. x(t)'); ylabel('distance (meters)'); xlabel('time (seconds)'); grid on; xlim([0 t_end]) end
