The unit can be anything. Principally, it is the distance unit per second.

Nice work, thanks! What exactly is the unit for velocity here?

anything in the attached zip folder? after my downing only a licence

Nice vectorized implementation.

A thought: It might be nice to include an additional argument so that the user could more easily use this function to evaluate intermediate points along the trajectory. Something like:
min_jerk(xi, xy, ti, tf, t)

1.1.0.0

Fixed: Wrong calculation after previous update.

Vectorizing the output, such that for loop becomes unnecessary.
Adding descriptions on the variables.
