Lisa wants to measure the depth of an empty well. She drops a ball from a height of 3
feet into the well and measures how long it takes the ball to hit the bottom of the well.
She uses a stopwatch, starting when she lets go of the ball and ending when she hears
the ball hit the bottom of the well. Her stopwatch measured a time of 2.2 seconds.
How deep is the well? (Neglect the speed of sound and air resistance).
