where
h (t) = 5+40t - 16t²
. tis in seconds after being thrown in the air
• height is measured in feet above the ground.
We can use this model to answer some questions like how high the ball will reach.
As a reminder, the velocity of the ball at time t is v(t) = h' (t) and the acceleration is at a (t) = h" (t).
(Side note on projectile motion: there are variations on this model, for example, if the ball is not thrown st
will not focus on those in this example.)
Question 1
1 point possible (graded)
When is the ball the highest?
