Using the formulas E_k = mv²/2 and W = Fs, find the amount of work done on a 5 kg object falling under gravity for 5 seconds

I know that F = ma = 5 * 9.81 = 49.05 but there doesn't seem to be enough information to find s

Thanks in advance

assuming there is no initial velocity (it was dropped not thrown downwards) you can use s=0.5at^2

Has any of urs done this question ?
