Falling object model When an object is dropped, the speed with which it falls continues to increase. Ignoring air resistance, its height h can be approximated by the falling object model: h is the object’s height above ground after t (seconds) h0 is the object’s initial height (in feet)

9. How long for an object to hit the ground when dropped from a height of 32 feet?
