<PRE><B>Question 949493</B>
A ball is thrown downward from a window in a tall building. Its position at time t in seconds is s = 16t2 + 32t, where s is in feet. How long (to the nearest tenth) will it take the ball to fall 110 feet
----------------
s = 16t2 + 32t
Use ^ (Shift 6) for exponents.
s = 16t^2 + 32t
s = 16t^2 + 32t = 110
16t^2 + 32t - 110 = 0
*[invoke solve_quadratic_equation 16,32,-110]
=======================
t =~ 1.806 seconds
Ignore the negative solution.
