The position of a free-falling object is given by
8(t) = - 4.9t + vot + 80
where s(t) is measured in meters, vo represents the initial velocity of the object, and so represents the initial
position of the object.
A ball is thrown vertically upward with a velocity of 15 meters per second, off of a building that is 250 meters
tall. Use the above position function to address the following prompts.
Determine the position function of the ball.
s(t) =
-4.9t2 + 15t + 250 v
Determine the velocity function of the ball.
v(t) =
-9.8t + 15 vo
Determine the acceleration function of the ball.
a(t) =
-9.8.
