Question 1061535
.
An object is thrown downward with an initial velocity of 5 feet per second. The relationship between the distance s it travels 
and time t is given by s=5t+16t2s=5t+16t2. How long does it take the object to fall 
74 feet?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Solve the equation

{{{16t^2 + 5t}}} = 74,

and you will get the answer.

(Which is t = 2 seconds).
