Question 399543: During a chemistry experiment, the cork in
a 0.6-foot tall beaker with an effervescent so-
lution pops off with an initial velocity of 23
feet per second. The quadratic model for the
situation is
h = −16t^2 + vt + s,
where v is the initial velocity, t is in seconds,
and s is the initial height.
How many seconds does it take for the cork
to hit the table?
Answer in units of sec.

Another way to ask the question is:
when is equal to zero?

Multiply both sides by

Divide both sides by

Use the quadratic formula:

(can't use a negative result)
also, the other root:

sec
check answer:
I'll see if this gives me

This is too big an error, but I don't know what
happened. The method should be good, though
