Solving Gravity: Initial Velocity & Time

[Sammiches]

I guess this isn't the proper format, but I would rather try and work out the complete problem on my own :\ If this is a huge faux pas then someone can go ahead and delete this post i suppose.

Now that that's out of the way, could someone tell me if it is possible to determine acceleration due to gravity knowing only the variables for initial velocity and time taken to once again reach to ground of an object launched from the ground vertically? And what would this equation be?
