The Search for Scooby Snacks
S cooby Doo is wandering back and forth across a straight line looking for Scooby snacks. His position, in feet, at time t is modeled by
s(t) = t2 – 6t + 8
where t is measured in minutes for 0 ≤ t ≤ 12.
Where is Scooby at t = 1?
What is his velocity when t = 4?
When does he stop?
Find his acceleration when t = 7.
What was his speed at t = 2?
What is his displacement after the first five minutes?
What is his average velocity during the first two minutes?
Velma finds a Scooby snack and throws it in the air. The path of the snack is modeled by
s(t) = -16t2 + 20t + 3, where t is in seconds and height is in feet.
8. How long did it take the snack to reach its highest point?
9. How high did the snack go?
10. When did the snack reach half its maximum height?
11. How long was the snack aloft before it hit the ground?
