How to create matrix array using while loop and time increment?

I have a problem where i want to solve a problem where an apple falls from a tree from 3m before hitting the ground. Assuming there is no air resistance, how long will it take to hit the ground? I have to create an array with time increments until the distance becomes 0 at the final time. So first column should show my time and second column will show the distance going down at every increment.
y0=2;
g=-9.81;
t = 0;
i=0;
y1=y0;
a = zeros([],2);
while y1>=0
i=i+1;
t=t+0.10;
y1=y0-0.5*g*t.^2;
a(i,:) = [t,y1]
end
disp(a)
0.0065 2.0726 %sample results
0.0065 2.0789
0.0065 2.0853
0.0065 2.0917
0.0065 2.0981
0.0066 2.1046
0.0066 2.1110
0.0066 2.1174
But when I run my code, it won't stop running and instead of 0.10 increments, the time looks off. How do I use the while loop (must use) to find the time it takes for the final y value to be 0.
