How to find the maximum/terminal velocity?

[Jessica Lewis]

In my grade 11 physics class we were asked to find the maximum speed of an object that is dropped from rest at a height of 100 m on Earth. We were given no information other than g = 9.8m/s2 and we have not done anything similar to this before, so how would you determine the maximum speed of an object? Are there any equations for this sort of thing?
Thank you to anyone who helps! :)

Well, you're most likely not looking for the terminal velocity, since you'd have to know several other things to find that (and possibly solve a differential equation), so assuming no air resistance, where during the fall would the object have the most speed if it's constantly accelerating?
