Lisa is measuring the depth of a well. She drops a ball from a height of h feet into the well and measures how long it takes the ball to hit the bottom of the well. The polynomial –16t2 +0t +h models this
situation, where 0 is the initial speed of the ball and h is the height it was dropped from. She raises her
arm very high and drops the ball from a height of 7.0 feet. Her stopwatch measured a time of 4 seconds,
how deep is the well?

Lisa is measuring the depth of a well. She drops a ball from a height of h feet into the well and measures how long it takes the ball to hit the bottom of the well.

Polynomial =  

where 0 is the initial speed and h is height it was dropped .

Now find depth of the well, when t = 3.5 seconds and h = 6 ft

=  

=  

= -196 + 6

= -190

So depth of the well is 190 feet (negative sign represents the depth, below the ground)

-190
