(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A hot-air balloon is ascending at the rate of 10 m/s at a height of 84 m above the ground when a package is dropped.

Find time it took to hit the ground

Find Final velocity

2. Relevant equations

3. The attempt at a solution

Initially, I am inclined to use the equation Yf = Vot + (1/2)at^2

I know that a=-9.8 m/s^2

Vo = 10m/s

Yf=84m

With four variables and 3 are known, I can find time.

The part I am having trouble with is setting up the equation where time is a function of velocty and position (where as t=something)

Am I even approaching this problem correctly? Any help will be much appreciated.

EDIT: Yes...my algebra sucks...:(
