Charlize wants to measure the depth of an empty well. She droos a ball into the well and measures how long it takes the ball to 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 in the well?
