Charlize wants to measure the depth of an empty well. She drops a ball 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. The polynomial
h = -167 + 6 represents how far the ball has fallen after t seconds.
4. How far has the ball fallen after one second?
5.
Charlize's stopwatch measured a time of 3.2 seconds when the ball hit the
bottom of the well. How deep is the well?
