Having difficulty getting the program right

Hello, I'm taking a minicourse on MATLAB and I was given an assignment that I am having difficulties completing. The assignment is to prompt the user for initial height (in meters), and vertical velocity (in m/s) and plot the height and vertical velocity as a function of time. I'm ending up with only a single dot. I assume it has something to do with my time variable, but given that I'm still early on in my education I don't know where to make the correction

The code I have is as follows:

g = -9.81;

h = input('Enter the initial height of the ball in meters: ');

v0 = input('Enter the initial velocity of the ball in meters squared: ');

t = 0;

h = (0.5)*(g)*t.^2+(v0)*(t)+(h);

v = (g)*(t)+(v0);

% Plot the height and veloctiy as a function of time

plot(t,h);

hold on;

plot(t,v,'r');

title('Position and Velocity of a Ball');

xlabel('Time t (seconds)');

ylabel('Height h (meters)');

grid on;

Make h and v functions of time. For example;

h = @(t) (0.5)*(g)*t.^2+(v0)*(t)+h0;

Also, make sure you use a different symbol for the input value (i.e. h0 not just h)!

And, of course, you'll need to supply vaues of t.
