SOLUTION: A ball is thrown from an initial height of 2 meters with an initial upward velocity of 11 m/s. The balls height h (in meters) after t seconds is given by the following
h=2+11t-5^
Question 1130803: A ball is thrown from an initial height of 2 meters with an initial upward velocity of 11 m/s. The balls height h (in meters) after t seconds is given by the following

You can put this solution on YOUR website! A ball is thrown from an initial height of 2 meters with an initial upward velocity of 11 m/s. The balls height h (in meters) after t seconds is given by the following
h=2+11t-5^2
Find all values of t fro which the balls height is 7 meters.
------------
Find the 2 times when the ball is at 7 meters.
Call them t1 and t2, where t2 > t1
----
t1 < t < t2
In my post, I simply want to notice that your basic equation is written INCORRECTLY.
The correct form is THIS
h(t) = 2 + 11t - 5*t^2.
Then solve it as Alan just explained to you.
