Should be easy for you guys here, but I am completley stuck on this one workquestion. They supply the answer(3.33 ,/s^2) , but not the solution.

I've tried searching online, and asking about everybody I know.

Anways, if anybody here knows how to solve this, I would forever be in your debt.

When an object is dropped from a height of 20.0m above the surface of Planet Z, it will fall 5.00m during the 2nd second of fall.

What is the acceleration of a falling object near the surface of this planet?


The formulas we are given are:

a = (Vf - Vi)/t

d = ([Vf + Vi]/2)t

d = (Vi)t + .5at^2

Vf^2 = Vi^2 + 2ad
