Charlize wants to measure the depth of am empty 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. The polynomial h=- 16t^2 + 6 represents how far the ball has fallen after t seconds. How far has the ball fallen after one second?
Charlize's stopwatch measured a time of 3.2 seconds when the ball hit the bottom of the well. How deep is the well?
