Octave does not like doing symbolic arithmetic with non-integer numbers. To
bypass that, use 'vpa' command (type 'help vpa' in octave command window for
more info). Basically, you should define v as follows:
v = (vpa(1/(60^2)) + vpa(0.8)*t) ^ vpa(-0.5);

Note also that I wrote 1/(60^2) and not 1\(60^2) since \ is the left
division so that's probably not what you wanted.

Additionally, if you want to evaluate acceleration a at a point, say, T1 you
should use 'subs' command and not 'eval':

Hope that helps,
