An object falls a distance h from rest. If it travels 0.42h in the last 1.00 s, find (a) the time and (b) the height of its fall.(adsbygoogle = window.adsbygoogle || []).push({});

so I know a=-g

and I believe I need to use v= v0 + at to some extent.

I also believe that they are trying to say that in the last 1s of the fall it traveled 42% of the total distance.

however because a=-9.8m/s/s and I am given "h" and not m I do not know how to incorporate that into the equation.

Greatly of appreciative of any help.
