Please help solve!

if the relation W=(F+X)/y, where W & F and force and x and y are unknown,is dimensionally correct then find the dimensions of x

How long will it take a ball to fall 81 feet

I was thinking about gravity and isn't it a meters per second per second per second acceleratory force? I mean, as you get close to an object's center of mass the force of gravity gets stronger,...
