Question
Need help with 3 parts on this code. Please edit my code, don't create a different code. 
 
I need help with the following code below. I labeled where i need help and where it ends. I also explained in the code what i need help with.
 
 
 
EDIT THIS CODE: 
 
% Create a program to plot the motion of the ping pong ball with drag.
% The program will take inputs for velocity in m/s and angle of launch.
% note that with a high speed camera I estmated a launch speed for a ping
% pong ball could be 30 m/s.
 
clear
clc
 
 
vel=input('input the initial velocity in m/sec: ');
angle=input('input the angle of launch in degrees: ');
% convert the degrees into radians so MATLAB likes it
 
angle=angle*pi/180;
 
% set initial position and time
x(1)=0; % meters
y(1)=.01; % meters
time(1)=0; % seconds
mass=.00247; %kg ping pong ball .00247 Kg
g=-9.8; % m/sec^2
c=-0.0005; % coefficient of drag with density and area in this constant
index=1; % so I can load an array for plotting
% start to increment the motion
velx=vel*cos(angle);
VelocityX(1)=velx;
vely=vel*sin(angle);
VelocityY(1)=vely;
% set a time step
deltaTime=.001 % seconds
height=y(1);
while height>=0 % it has not hit ground yet
index=index+1;
% break velocity into its components
velx=vel*cos(angle);
vely=vel*sin(angle);
 
% NEED HELP HERE START
% use an if/else statement to check to see if the ball is moving
% down (negative). If it is, then drag has an opposite sign
% as gravity in the acceleration formula. Otherwise gravity
% and drag have the same sign. Calculated the acceleration
% in the y direction inside the if/else statement.
% Now calculate the acceleration in the x .
% *******************************************************
 
% *****************************************************
% calculate the new velocity at the end of the time step
% this will have X and Y components, so you need a variable
% for each. One is velFinalX and the other is velFinalY.
% *******************************************************
 
% ******************************************************
% Get a new velocity vector and angle given the X and Y
% The velocity is the variable "vel" and angle is "angle"
% NEED HELP HERE END
 
% now save my values at this time step
time(index)=time(index-1)+deltaTime;
VelocityX(index)=velFinalX;
VelocityY(index)=velFinalY;
 
% and distance numbers
distX=velx*deltaTime;
distY=vely*deltaTime;
 
% save distance values
x(index)=x(index-1)+distX;
y(index)=y(index-1)+distY;
height=y(index);
end
