Exit Ticket for Lesson #3.6 An object is fired upwards with an initial velocity
of 112 feet per second. Its height, in feet above
the ground, as a function of time, in seconds
since it was fired, is given by the equation below.
h(t)= -16t2 +112t
a. Determine at what height the object was
fired.
b. Calculate, algebraically, the time that the
rocket reaches its greatest height and the
maximum height.
C. Calculate, algebraically, the time when the
rocket reaches the ground.
d. Sketch the graph of this function, labeling
all important points you found.
e. Justify your thinking using math evidence
and vocabulary
