During a chemistry experiment, the cork in
a 0.5-foot tall beaker with an effervescent solution pops off with an initial velocity of 13
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?

@ganeshie8 Can you help please ?

ganeshie8 · Answer

substitute the given values into the equation

ganeshie8 · Answer

$$\large h = -16t^2+vt + s$$

ganeshie8 · Answer

whats the initial velocity of cork ?

ganeshie8 · Answer

whats the initial height of cork ?

anonymous · Answer

h=-16t^2+13t+s

ganeshie8 · Answer

yes,the cork is on a 0.5 foot tall beaker so the initial height = s = 0.5

ganeshie8 · Answer

plug that in also
