## Homework Statement

A hot air balloon is released from the ground & rises up with a constant acceleration of 4 m/s^2. When it is 16 meters above a sandbag is dropped.

What is the time taken for the sandbag to hit the ground?

## Homework Equations

v^2=u^2+2as

v=u+at

## The Attempt at a Solution

v^2=u^2+2as

v^2=0+2(4)(16)

v=11.31m/s

v=u+at

11.31=0+(4)(t)

t=2.828
