Question 1119939: An object is dropped from the top of ABC Tower, 1,500 feet from the ground. Calculate the average velocity of the object over the interval t=2 seconds and t=3 seconds. The position function of the projectile is s(t) = -16t2 + V0t + h0, where V0t is the initial velocity of the object and h0 is the height to which it is dropped.
Answers:
at t=2 seconds, s(t) = _____ feet
at t=3 seconds, s(t) = _____ feet
average velocity = _____ ft/sec

An object is dropped from the top of ABC Tower, 1,500 feet from the ground. Calculate the average velocity of the object over the interval t=2 seconds and t=3 seconds. The position function of the projectile is s(t) = -16t2 + V0t + h0, where V0t [sic] is the initial velocity of the object and h0 is the height to which it is dropped.
Vo is the initial velocity, not Vo*t
--------
Answers:
at t=2 seconds, s(t) = _____ feet
It's s(2)
Sub 2 for t.
====================
at t=3 seconds, s(t) = _____ feet
Same as above, t = 3
=========================
average velocity = _____ ft/sec
= s(3) - s(2)
