If your object starts at rest. e.g. 0ms^-1
after 1 second it will have gained a speed of 9.81ms^-1. And therefore travelled 9.81m. After 2s the distance will be 9.81 + (2 x 9.81) = Ans
you need to use equations like:
v = u + at
v^2 = u^2 + 2as
s = ut + 1/2at^2
s = (v + u) / t
a= acc due to gravity (9.81ms^-1)
As long as you know some of these values you can re-arrange the formula's to get the other ones.
Hope that helps a bit.
