How to Stop FOR loop when "answer" is reached, and display answer?

Simple "throwing a ball" physics problem - someone throws a ball, I want to know what time the ball touches the ground.

I am trying to create a loop that "stops" when the height of the ball reaches 0.

Then I want to display what time the ball reaches height = 0.

Here is what I have sofar:

%When does ball Reach the Surface?

for t = 0:0.01:6.2

if height_earth = 0

disp('The Time when the ball lands is: %4.2f\n', time)

else

disp('The Ball doesnt Touch the Ground')

end

end

I get the display "The Ball doesnt Touch the Ground" 621 times, and have a feeling if "if height_earth = 0" were valid matlab syntax, a would get the entire time array.

See the documentation on the break function.

What about for the solving? How would I get it to display the time when height = 0?

Put the break call after the disp call.

Also, the comparison requires a ‘double equal’ —

if height_earth == 0

.
